I get the gripe that reviews have had with Last Survivor cutting off abruptly, but I also don't think they couldn't have pulled off the sequence inside the Narcissus after that. They would have had to do a scripted Alien, because its AI doesn't have it sitting around staring at you like it does in the film.
Definitely agree on the death scene thing. They didn't try to replicate the audio and I really wish the music would've been from the movie.
