OMG This is going insane. You people need to relax.
You're acting like this will ruin the whole movie. Oh, come on...it's not like we are going to see Chet vomiting in people's mouths from bed to bed for 30 minutes. I, for one didn't like the idea at first, but it works somehow, it's surelly a lot better than egg morphing (which is freaking absurd - I saw the cutted scene from Alien two days ago and it seemed so out of place, I felt like it screwed the whole movie). We'll just have to wait and see how it turns out. If it's such a big problem - don't see the movie, no one is forcing you to watch it.
