But we did see him shirtless and all of his muscles
Miam! Miam! Miam!!!!!!!!!!!!!
It makes me think of You're Just My Love.
Basically what he says is, 'I love you so much that every time I'm around you, I become full of life'.
Which taking into account Mamoru's character/past means, whenever he's around Usagi, Mamoru realizes that he has a reason to be happy and alive

Usagi gave him a reason to be.
(Unfortunately, Mamoru was shafted past R, it would have been a cool road to delve more into his character but the R Movie exists!)
I think the culture of binge-watching has definitely contributed to this (and not just on watching 90s 200 SM episodes).
For example, I love Mike Flanagan's Netflix shows - they are really good. However would I, personally go watch them again? No.
Because the format is catered to be binge-watched.
It's not a pacing issue but more so how the episodes are structured - the episodes themselves are really long and there's loads of information in each of them. You can't really take it at one episode a week. Sure, you'll not forget everything but you'll definitely miss something here and there.
I do not have the time to binge watch a 12 hour show.
On the other side, I really like to watch the Lincoln Lawyer.
Or even the Lockwood and co series (a shame it was cancelled).
Lockwood has only 8 episodes but the episodes have sufficient info in each of them so that I can watch the series at my own pace. It's much more relaxing to go back to the series.
Which is why I prefer the TV shows of the last decade. I've been watching Law & Order SVU on Netflix and I can take any episode at any time and just enjoy it because they are stand-alone stories.
Even series such as Bones or Supernatural that had an overarching storyline have more breathing time in between to relax.
When it comes to Sailor Moon, it seems a lot of people's mindset is 'it takes too much time to watch the 200 episodes, I'll go for Crystal because it's shorter' as if it's a race to finish the series.
It's a show not an exam to cram!
Take it at your own pace, it can be an episode a day or a week - it's entertainment, it's meant to be experienced.
You know this is why I don't understand when people say the 90s anime is full of holes compared to the glorious manga...
And also, the manga doesn't have plotholes,
it's meant to be imagined...
Cause don't get me wrong, the 90s anime HAS giant plotholes at times.
Like for example, a lot of people hate the animosity of the Outers and Starlights but I like it - conflict add layers to the story and having all characters agreeing with each other all the time would be plain boring as history proved it with the manga.
It's poorly implemented but it makes sense story wise - the Starlights are invaders and they are bringing their own conflict as they are being pursued by Galaxia to Earth.
In UraNep's mind, the Earth has nothing to do with this and they should vacate immediately. It kinda reflects real-life territory issues.
However, it's completely bonkers how nobody questions Chibi-Chibi!
Even Pluto doesn't know who she is, all of the Inners have sensed she has a mysterious power, she has ungraded Moon and UraNep is like 'OK, little weird doll-looking girl. You can live with Usagi, no problem'.
It's an issue that stems from the manga in which again, nobody questions or suspects the origins of Chibi-Chibi (despite every one there is supposedly
super mature) and the situation is played for (poor) laughs.
My biggest issue is Mamoru 's plane. It just doesn't make any sense!
A Japanese airline with about 200 passengers just goes missing and it doesn't make the headlines?!?
I understand it was in the 90s with the internet/smartphones not being an everyday thing but still lol
Anyways, all of that to say that despite people claiming Galaxia doesn't make any sense in the 90s anime, on the contrary we do have little hints via the characters' dialogues or actions that paint a picture (which people fail to see I guess).
First when Galaxia attacks and kills Mamoru, he confesses that Earth has several allies of justice who will stand in her way.
We can hypothesize that the reason she doesn't immediately launch a wholesale attack on the Earth is to entertain herself one last time considering Earth is the last remaining inhabited planet in the Galaxy.
So she sends the Animamates to create some amusement for her.
But there are mainly 2 important things that we discover that explain her actions:
1) Throughout the season, Galaxia comments and notices that a great deal of Senshi are reuniting in the remote planet that is Earth (compared to the manga where our Solar System is the best in the galaxy - barf! it's like S5+ Charmed level of writing).
Galaxia is deeply concerned and disturbed by this phenomena and tries to understand it.
2) As we discover later, there's only one thing Galaxia is scared of and that is the Light of Hope, her own Star Seed.
She has knowledge that she sent her Seed into the universe to one day find someone who could nurture it.
Earth being the last remaining planet, it would have sense to her that if the Light of Hope survived, it would be found somewhere here.
Her greatest fear is that it has already found a host and in due time, that person will release the Light that would seal her away.
To me, this is the reason why she sends the Animamates into a wild goose chase on Earth, the 'True Star Seed' that Galaxia is searching for is not a random one but her own.
Via the Animamates acting as her eyes and ears, she is monitoring the situation on Earth with all of these Senshis and as well as trying to lure out the Light of Hope.
It is implied that she thought Kakyuu would have been the one to inherit the LoH.
Galaxia knows Kakyuu survived and Kakyuu is the last remaining person who has the requirements to don her Star Seed.
When she first lays eyes on Kakyuu, Galaxia says, 'So you're the one intending to release the power which can seal me away'.
However, once Galaxia discovers that Kakyuu has appeared but not the LoH, she judges she has nothing to fear.
She, herself, descends on Earth, gets rid of Nyanko (since now she has no use of the Animamates), kills Kakyuu and launches an all out-attack on Tokyo.
She lets the girls live instead of killing them as entertainment for herself.
Honestly, all of this would have been less confusing if for example one of the Animamates had the simple line of, 'Oh, so what you're a Senshi? I could care less about your 'True' Star Seed, I'm looking for a grander one'.
Or if an Inner and Animamate had a brawl with the Inner losing, the Animamate could have claimed something along the lines, 'Huh! I have no use of your True Star Seed. Madam Galaxia requires one that shines with the absolute light. Now die!'
Compared to the manga where Galaxia is a big ding-dong whose plans make no sense!
She could have killed Usagi at the airport but chooses not to. Usagi goes into shock - is it Galaxia's doing? I don't know.
Galaxia, at one point, confronts Usagi and destroys Tokyo to only flee because of Chibi Chibi so why didn't she kill Usagi back then???
Some people will say it's all for Usagi to have 'the strength' to confront Chaos and Galaxia wanted to pit the two against each other.
Except!
Usagi is claimed to be the sole person to rival Galaxia. Rival means she's the only one who can stand on an equal footing as her.
Yet when they do duel, Usagi is overpowered and Galaxia just... gives up and flees to the Cauldron like a big moron.
How could Usagi have been a match with Chaos (who is more powerful than Galaxia) when she was barely a match for her.
And still! Usagi was never a match for Chaos! She had to conjure ALL of the Senshi slumbering into the Cauldron to extinguish Chaos.
Also, Galaxia really believed Chaos wouldn't backstab her?
In what world does Galaxia's plans in the manga have any sense and why nobody talks about it?
