Best in Show was a comedy. It's like a mockumentary, and it wasn't to be taken seriously. It was poking fun at crazy dog people, and wasn't supposed to be a real life story or anything like that.

My votes for crap movies are so long. Nearly everything these days sucks. Here are some I can think of that I really didn't enjoy:

The Other Sister
The Affair
Forrest Gump
Green Mile
Beautiful Mind
Titanic
Grease
Dirty Dancing
As Good As It Gets
I Am Sam
