Neither sequel comes close to the cathartic simplicity of the first one imo. Heaping on a load more plot took away the straightforward drive, and ultimately the action scenes, stylish as they are, are just more of the same over and over.
Case in point - my main gripe with the second movie is that the opening action sequence is by far the best it gets, probably because it's the only one that feels like I hadn't already seen it in the first movie.
