After seeing the trailer, I can say that at first look, it at least, has the feel and look that the Hitman games have done pretty well.
Even in the music for the movie trailer, it felt like something I could see being in the game. Is Jesper Kyd doing the music for the movie??? You really can't do a Hitman project w/out Kyd composing, if you ask me.
About the movie trailer being trigger happy, well -- yeah, you could do that in the Hitman games, but you'll likely finish a level with barely any health, if you do. It ain't easy to finish a level like that. If the movie does goes the trigger-happy route, let's hope in the movie, he comes up pretty beat-up.
Trailer was much better than I expected. Let's hope the movie turns out decent b/c a lot of the video-game-to-movies transitions just lose something, in the process...Namely b/c I'd guess it's real hard to make a 6-15 hour game and condense it into a 1 hr 1/2 to say 2 hour film...
