Jim Carrey and Jeff Daniels in Dumb and Dumber To.

After numerous stops and starts, the Dumb and Dumber sequel has finally made it to the screen, 20 years after the original.

Jim Carrey and Jeff Daniels return as Lloyd and Harry, movie history’s two biggest dumbasses. While Carrey slides right back into the role of the mischievous goofball, Daniels seems to be forcing it a bit, so the chemistry is off. Even worse, Bobby and Peter Farrelly make their two stars labor for laughs with a script loaded with hit-and-(mostly)-miss gags.

The plot involves Harry finding out he has a daughter, and the two going on another road trip to find her. (Harry also needs a kidney, thus the need to find the daughter, for donor purposes.) There’s a gag involving an old woman under the covers that I can’t believe made it into a PG-13 movie, and a couple of other decent laughs—but the chuckles are far and few between.

Diehard fans of the original will be happy to see these characters back, though the happiness will be accompanied by the sadness of wasted opportunity. An after-the-credits scene claims there will be another sequel 20 years from now. I’m hoping that’s a joke, because there really is no need to visit these characters again.

I can’t believe how nasty this film is to Kathleen Turner. I’m a little mad at myself for thinking the way she’s taunted is the funniest thing in the movie.

Dumb and Dumber To is playing at theaters across the valley.
