I'm afraid they're right.
This blog's about comics so I'm going to keep this brief and spoiler free.
Saw Prometheus yesterday evening and was thoroughly disappointed. It looked gorgeous and was well acted but . . . was rather boring. Wasn't engaging at all; you just knew all the characters except the obvious were there simply as cannon fodder; if the surprise passenger was meant to be a surprise it didn't work; and the continuity nerd in me wanted it to tie in better with Alien than it did.
The best part about it? Seeing a trailer before the film for Jaws getting a re-release in a couple of weeks!
