Here's the thing: as far as being a quality movie goes, it's bad. Cheap plot that rips off Hitchcock and weak dialogue, in addition to other pieces. As far as entertainment, this movie is absolutely off-the-wall with action in every annex. The shootouts are awesome and the whole finale is just insane with explosions and gunfire throughout the chase.
However, in comparison to the others, it's the weakest of the series. Third one's awesome, but the first is undeniably the best. DePalma's a hell of a director.
