Prequel to Dumb & Dumber is an incredibly bad attempt at outdoing the original. Where to begin? The acting is terrible, the jokes are unoriginal, the script is terrible. This film one of the worst films that I have ever seen, and it doesn't deliver anything funny or amusing. The film instead of being funny is irritating with it's stupid attempt at "good" comedy which of course fails fails on all levels. If you're lucky you'll stay away from this film. If you're unlucky, you can warn fans of Dumb & Dumber how bad this prequel is. This film scrapes the bottom of the barrel and goes further still. All the actors here for exception of Luis Guzman suck. I'm actually surprised that Guzman acted in this. Dumb & DUmberer is actually a fairly great title for this film because it certainly is dumberer and makes the viewer feel dumberer for having watched it. Thnere's nothing great about this film, it's a dreadful train wreck of a movie that you wished you hadn't seen in the first place. The film is thebtype of movie that you wish could be unmade and whipped off the face of the earth. Dumb & Dumberer is nothing but a sorry piece of crap prequel thatjoins a few other films that filmmakers have tried to cash in on its far superior counterpart. Of course I'm refereing to films like Slap Shot 2, 3, Sandlot 2,3 and Caddyshack 2. All of these films failed to capture what made the originals so great. Now Dumb & Dumberer is among those sad, mediocre titles as one of the worst prequel/ sequel ever made.
