The main reason I've wanted to see it on Netflix is to get improved subs, as no fansubber ever came through with good quality and accurate ones (as far as I know). The trailer... isn't exactly making me optimistic of that.
Why is Galaxia supposedly just saying "[Is] The future you know is really the future?" and Moon saying "[Because?] That there are things that only I can do". (Words in brackets are my additions as to what's seemingly missing) They're fragmented portions of what they should be saying. I don't know if they ripped the subs from the scenes without additional context or cutting off the rest of the sentence, but it's pretty pathetic for a trailer this short to have broken English...
