The first one is okay but it's too much of a spy movie for me. I'll watch it but it's definitely not my favorite.
The second one was great...introducing Fat ******* was great, he's such a horribly disgusting character.
And the third one was HILARIOUS -- I LOVE Goldmember. Mini Me crossing over to Austin's side was great -- we used to rewind over and over when they're in the ship and he comes flying down that laundry shoot and slams into the wall when Foxy opens the door.
Out of all characters, Dr. Evil is my favorite.
