Great action sequences, boring everything else
First of all, Polito comes across as a cartoon figure to me so I could never take him seriously whatsoever when he was on the screen. I felt like if he met a guy from Goodfellas it would just result in defenestration within seconds.
So whenever he is onscreen he just sops up any of the film's momentum and energy.
The screenwriting is poor. If you've had a screenwriting class you could probably spot the errors literally within the film's first few minutes. In the dialogue they refer to so many events that we haven't actually seen and characters who we haven't been introduced to yet. It's fairly confusing and extremely dull.
Finally, the Bernie character is intolerably smug and weaselly. He was allowed to live far too many times.
