I think most people will agree that Mission Impossible is great franchise, but for me, I hate the second one. It's like an ugly stain on a perfect franchise.

It just stands out from the rest and doesn't feel like it is part of the same world.

John Woo is great director, but even for him, it's not one of his best movies.

Can you think of any more amazing franchises with one ugly duckling?

EDIT:

That said, I did find a seriously intense behind-the-scenes video of stuff that happened on M:I2. It's not for the faint hearted.
