Not as fun as the first movie since it's a lot more reliant on special effects and feels much more gimmicky as a result. The plot isn't that great and of course, the fact that they had to spent most of the first part of the film getting Kay's memory back can be a bit draining after you've watched it the first time. The humor still works but the laughs aren't as great, a few sections can feel forced, as if the writers have ran out of ideas. As mentioned, there are too much reliance placed on special effects to the point where it feels like there's nothing else going for the film. A lot of the actions are exaggerated and you can't help but think of the number of people that would have noticed something and how the Men in Black could so easily miss one or two when wiping everyone's memories. It's was amusing to see Agent Jay acting so mature and knowledgeable at first but then going right back to his rookie roots when Kay was back. It's still a fun movie to watch though.
