Pros:
George's (the gorilla) sense of humor.
Much action (mostly at the second part)... after all that's the primary thing you ask from a movie based on a video-game.
Cons:
Scenario 1/10 ("Characters" and "plot" are two words that this scenario doesn't know what they mean... some scenes are outrageous unreal).
Direction 4/10 (Peyton didn't avoid the clichés, although some action scenes are well made).
Dwayne Johnson 3/10 (But that's OK, it's Dwayne Johnson, you know what to expect).
Jeffrey Dean Morgan 2/10 (He looked like a bad immitation of Robert Downey Jr).
Naomie Harris 5/10 (She was decent, in comparison with the other actors of the cast).
If you are a Dwayne Johnson and video-games fan this is what your looking for. I'm not. 4/10 by me.
