5. 'Dumb and Dumber To'
The good people behind Dumb and Dumber To had a tough task: how to follow up one of the most beloved comedies of the past 25 years, particularly considering that almost every comedy sequel in history has been a disappointment? For every one Addam's Family Values there are 75 Crocodile Dundee in Los Angeles trainwrecks. Jim Carrey and Jeff Daniels gave it their all, but the road trip-themed movie felt too familiar and not nearly enough of the jokes connected. That said, we love these characters so much that we'll be first in line for part three.
