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.
I value your opinion highly, and I think I will reassess whether I watch this movie sometime or not because of that.
RedLetterMedia doesn't always land good takes, after all.
It's at the very least an enjoy able C+/B- to use the classic lettering rating scale. It's not at all a bad film. Very watchable. Not the greatest piece of sci-fi cinema, but it is at very least a real-ass movie. Very much above slop, well in the realm of film for sure, not cinema or anything but it's solid.
