First I was excited, then i watched it again.
I hate the music in the trailer, I honestly think it's garbage, doesn't fit and i find it distracts from the trailer overall. I know it won't be in the movie (or hopefully used again), but bad choice of trailer music always sullies my experience (I tend to be hyper critical of music choices i find ill-fitting) and makes me question seeing the movie in a theatre (I'll still go see it).
The Shower scene looks exactly as cheap and tacky as I thought it would. Thanks for that AvP:R-esque moment in there. That's just great.
Honestly I want to be excited. I'm not, and will echo the "it looks like a cheap 90's horror movie". I am comparing my reaction to the Prometheus trailer, and while that film wasn't as good as it could easily have been the trailer was filled with splendor and wonder. It showed neat parts of the culture and took you further into the Alien universe (also the music cues in that trailer and the music itself f**king rules). This looks like a random Dark Horse comic brought to life.
I watched it a third time with the sound off. If I didn't know this was an Alien movie, I'd have a hard time believing it took place in that universe. It looks like a really well shot (the colour palette is great) stock horror movie.
The Prometheus trailer lived and even exceeded the hype surrounding that movie, this trailer has brought my excitement down a few notches (beyond maybe the backburster part).
