We had a perfectly fine sequel with Cardcaptor Sakura Clear Card that had solid animation and production value issues that plagued Crystal but fans still complained about how Clear Card turned out. It will be the same thing with a Sailor Moon sequel as well. It's not just towards Crystal but I sense a lot of cynicism towards the franchise as a whole. Most fandom discussions these days seem to be complaining which version of the series is the worst, dub wars, political rants about the series, rants about Naoko, rants about Ikuhara, nitpicking apart plot holes and inconsistencies and the fandom just feels tired these days. I just want to finish collecting the show and for Crystal to finally finish and then I can move on to something else.
Production value is not the only thing fan wants, Production values of the season 3 of Crystal was excellent. the problem came from the story, it's just the manga and the story of the manga is average at best.
And it's the same problem with Clear card, the sequel was just unecessary, Sakura ending was excellent and the story of Clear card is unecessary but also uninspired, it add nearly nothing to Sakura.
It's the problem of making a sequel, a Good sequel need to be need or if it's not it need to be inspired, retelling nearly the same thing that the old serie but not as good is a problem.
Actually it's why changing the cast, where happen the sequel or setting the sequel many years after the original allow to make better sequel (when the staff don't make fanservice like in Starwars 7 and just retell the same story than before but with new character)
Actually it's why I would have loved a nearly tottaly new cast for the serie and the old cast being only see in flashback (and Chibi Usa being here but old and only as Support character)
Actually I think a good sequel or reboot need to but respectful of the original serie but need to ignore the fans and.
Some exemple of good sequels in animation for me is Last Exile fam and the season 1 of Saint Seiya Omega and a good exemple of Reboot(much easier than sequel) is Lupin 4th serie, Gatchaman crowds and Casshern sins
Glitter Force is no success, if it was then it would be selling loads of merchandise by now like Precure is in Japan.
Actually the goodies have been ordered to Hasbro but Saban went bankrupt because Power rangers movie so they where unable to pay it.
And actually the serie being on Netflix, Toei animation don't need the serie being a big hit, as the serie is shown non stop every years Toei received money every years and Saban need to pay Toei even the serie is not a succes. It cost many money to Saban but for Toei, it's a success.
On the financial report it's shown Glitter force earn as much in west each year than Saint seiya in the whole world each year between 2007 and 2015 (and saint seiya was the 4th biggest licence of Toei animation), Glitter force earn 2 time more what a good season of Digimon earn.
Actually Glitter force earn to Toei more than sailormoon was earning each years to the studio during 90's
So Glitter force seem not to be a success and it's maybe not for Saban (if it was really not Hasbro would have not by the rights of the serie) but it a big success for Toei animation as Toei is paid even if the serie is a failure
TOEI get more than enough from Bandai to produce it each year - the whole concept with cute fairies is invented to sell toys. Precure is the Pokemon version of a magical girl show. With Sailor Moon things are different, it sells props and figurines, but it doesn't enough mascots.
actually, not so much anymore, nearly every Presentation material released with the Financial report since 2015 comment Pretty Cure revenue as being weak, the financial result included what the studio earn by Bandai, so the sales of Goodies are decreasing too and Sailormoon Crystal earned nearly at much.
Actually if Toei had replaced Precure with a new sailormoon, you could be sur the design would have been rethink to sale more toys, with Luna and Artemis (or there successor being redesigned to look more like Hummy from Suite Precure)
And actually not being a failure in US don't mean being a failure in the whole world (by exemple, France by 10 times more manga than the US, from a French point of view manga are not popular in US)
I have talked about Saint seiya, it's the 4th biggest licence of Toei animation but it's just not popular in US.
Maybe Glitter Force worked out of USA.
