They always tried to tell me it was the drugs or the war but know I know the truth; it was Agents J (Will Smith).
Yes it was more of the same as the first two productions. It is not easy trying to top the original movie let along making something coherent and excel with new one-liners.
Yes why not time travel, revenge, and evil. Who would ever expect something hidden in a cake being brought into the jail?
I will not go into detail as that is the fun of the movie as secrets review themselves. I was really surprised to see anyone pull off a young agent K; Josh Brolin pulled it off quite well.
If there be a MIB 4 I"ll be there.
