Someone's taking themselves a little too seriously. Maybe this is just what happens when you make a trilogy from a sleeper hit comedy- it just becomes overblown. While this is fresher than Part II, there's a stinky misanthropy lingering about it. On the plus side, it looks amazing, and even when the big setpieces aren't funny, they're very ambitious.
Finally got around to watching this, and loved it. It teeters on the edge of controversy, but it's ultimately quite sweet. Reno and Portman are wonderful together. Also, it has Gary Oldman going full-baddy in every single scene in which he appears, which is always special.
