OK we have all seen the previews... but the movie is so worth seeing. 3D is awesome way to see it. When J jumps of the building...it looks as if he gonna landed on you. Movie starts out with Zeds death and agent O taking over Mib. The fight with the alien fish was so funny. J puts mustard up its nose..inturn the fish sneezes J out the window. Then K disappears and J time jumps to 1969. Its so funny the bikes they ride are so cool. J lays it the bike down on its side and slides under a truck. J and K go to the dinner for pie to think about things. Then they go to a fashion show where they meet up with this Guy who sees multiple futures. The Guy helps them get an device attached to the Apollo lunar launch. As K fights the younger alien J fights the one from the future. J jumps the alien and keeps time jump back a few minutes. It is weird but funny. J punches the alien the last time knocking him off and killing him. K kills the younger one after the alien shoots the solider who helped J and K. The ending of the movie is a shocker. I kinda teared up. It truly explains everything about J being an Mib agent for 14years. So if you want to know the secrets of the universe, GO SEE MIB3. You will be surprised.
