The pic of Ridley in the alien suit is really stupid. This isn't one of those announcements that makes you think 'oh COOL they're gonna do a good one!'.
I'll see it though, I don't have a particularly high bar for space movies, I'll go see pretty much whatever in that area up to a point.
I'm cool with Sigourney Weaver returning, or not. It really doesn't matter if the story is fun, it's just a question of what they do. It's like Terminator - yeah, Arnie isn't what he was, so just don't pretend he is and do a thing where he's an old man that somehow fits into the universe (I'm not saying this is what they've done with Genesys, I'll wait and see it, it looks bad). You could do an old woman Ridley and have her be a main protagonist which is still relevant, but if they just ASSUME Ridley is important and shoehorn some plot around her which doesn't fit her age anymore, then it'll be weird and it means their priorities are all fucked up when it comes to telling a fun sci-fi horror story.
It won't be horror, though. It'll be some PG-13 CGI action thing, so I guess I just hope it's mildly entertaining for what it is. Otherwise, who gives a shit!
