I also thought Frank was horrible, but I didn't find Room to be that great either, except for the performances. Didn't really seem to have any great impact on me, aside from a couple of moments. The kid is the real standout, but the whole drama situation of the second half seemed a little heavy handed. Also, the directing could have been much better if there was a real work on the sense of space, which is one of the main themes of the film and didn't really show in the visuals. Especially in the first half, when it reminded me of Danny Boyle's handling of 127 Hours, by choosing to do a lot of cutting and points of view to not bore the low attention span audiences, when I felt it should have been way more restricted, more contained. The scene where the kid escapes is nice enough, but then again, someone with a little more sense of suspense building could have made it truly unforgettable. I don't seem to like this Abrahamson dude very much, it seems. Then again, I seem to be on the minority here, this apparently is a crowd pleaser.
