Name a successful franchise that doesn't contain even one good film

The only stipulation is that the franchise must have at least three films.

For me it's Madea. They're amateurish in a bad way and aren't even mildly amusing let alone funny except maybe to a 9 year-old. I've just never seen a Madea movie that I found entertaining in any way. If anything, I find myself irritated after watching these Tyler Perry turds.

So, what are your picks?
