There was some sketchy dialog particularly noticeable when Dolph's character max was speaking with his fellow soldier while they were walking on the bridge early in the movie, and some of the acting was stilted, but I loved that the zombies moved quickly and the robots were fun. The Dolphster is getting old, you could tell by his movements, especially when he runs, but he is in excellent shape. Dolph plays the part of the stoic unwilling hero well. The CGI was not Lucas film quality but it was not distracting. The main characters had clear personalities and weren't all generic. I only wish the end wasn't so predictable as to who would survive.
