Reading his review, it sounds like he really didn't like it. He said the shooting was mundain, and he mentioned that the powers and cool down didn't seem to flow well. And he didn't appreciate the wrinkle that time-suit equipped enemies added to the gameplay. He wasn't really feeling the story, nor the live action episodes.
It didn't really seem to like anything about the game really. so I'm not surprised he gave it a 2.
I AM surprised that his opinion on just about of these issues is the exact opposite of how most other reviewers felt about the very same issues...
But hey, that's how opinions work. And he's certainly entitled to his.
