Seriously, there was a half-hour of commercials before the movie. An eight minutes Blu-Ray commercial. Two video game commercials. One for some film group. Plus the usual handful of trailers. None of this could be skipped or advanced through, which made a two and a half hour movie that much longer.
I don't know why the movie didn't click for me, but I was bored with it from the first moments. I made myself sit through it, thinking it must get better, but other than the special effects I couldn't care less. (And, on a small screen, even those special effects weren't all that much.) I really don't know if I'll bother with the last half-hour, I feel like I already wasted two and a half hours of my life on this.
Edit: Okay, watched the ending. I liked it more than the rest of the film. Googling let me know that I wasn't alone in being uncertain if he was still dreaming or not when he got to see his kids, and I liked that. I also really liked how they brought the end of the film right back to the opening scene. The ending made me feel a little less like I wasted hours on this, but I still wish the film had been a whole lot shorter.
