one thing I knew for sure is that Martin Freeman will deliver, I could tell just by looking at the trailer. Saw the movie 4 times so far, always in 48fps. Don't forget you haven't actually seen any movies so far in 48fps so you are bound to feel "differently", so don't dis the movie just because it felt too fast or unnatural.
ps. too bad they didn't shoot it in 60fps like the original intention, that would have been SICK!
