No, I haven't seen it. Yes, I know RedLetterMedia is not an infallible source of movie criticism. But when I read about the movie myself, from promotional material for it no less, I found myself asking "that's it? That's all there is to this?"
Maybe my interest/fondness of the franchise hasn't fully recovered from that "David actually made the alien and killed all the Engineers" retcon asspull from before that made the universe feel very small and stripped it of a lot of curiousity and dread in the darkness of space and all of that.
If you saw it and liked it, that's great. Share what you liked about it if you like. The set design, physical costume/makeup work, and even the acting all sound promising, but I don't think I could bear to sit through what really does sound like some LLM-written kitbash of the previous movies.
spoilers, discussion of SA
Early in the film, one of the characters reveals she's pregnant, that the father was an asshole, but that she's excited to have the baby. At the end of the film, she gives birth to a monster. A fully-grown man-thing that's more sexual predator than human. How do you make a thirty minute "review" of the film and have nothing to say about this motherhood and patriarchal violence?
