Agent J goes back in time to save Agent K's life, and to kill the Flight of the Conchord's alien guy.
You'll never guess what happens.
It was very nearly almost funny at some points. It DOES have the tiny, yet hugely annoying, aliens in it, (but only for about five horrible seconds.) The ending was sweet, the middle was boring, and the beginning was badly written. The dialog was ground breaking... but not in a good way.
I'd say it was better than the second movie, worse than the first. Is that what you wanted to hear?
Josh Brolin did a wonderful job being Young Tommy Lee Jones. They should make a Fugitive prequel. (That was a joke! Don't do it!)
Oh, and GOB was in it!
