16. OCEAN'S TWELVE (2004)
Clooney and Co. forget what made Ocean's Eleven a gas, drowning their sequel in smug inside jokes (Julia Roberts' character impersonates Julia Roberts!) and painful additions (Catherine Zeta-Jones as a leather-clad world-class sleuth? Villain Vincent Cassel eluding infrared alarms by break dancing?). This is a bunch of zillionaires dishing out more of the same and expecting you to lap it up, say thank you, and tip the waiter.
