Men In Black 2 was a real disappointment for me. While the actors did a pretty good job, especially Smith, there just isn't a cure for a poor script once in production. The movie really had a "sequel" kind of feel, playing off partial events of the first film. The story was, in a word... bad, at best. It wasn't thought out well, and seemed very choppy and incoherent at times.

In the first flick, the MIB Organization had a kind of "elite" force feel. You had a few special agents, and it had a "clandestine" kind of feel to it. In the sequel, the MIB Organization has a JROTC Summer Camp vibe.

The movie wasn't terrible or anything.. it just lacked the "coolness" (for lack of a better phrase) of the first movie. A lot of the same old humor was recycled from the first to the second, and didn't really add any originality to the MIB Universe.

A perfect analogy would be Episode 1 to the first 3 films. Was it decent? Yeah. Is it worthy of bearing it's title? Not really.
