DUMB AND DUMBER TO Coming in 2034: Dumb and Dumb3r.

CHECK YOUR CALENDAR. Yep, it really has been 20 years since Dumb and Dumber came out. Directed by the Farrelly brothers and starring Jeff Daniels and Jim Carrey, Dumb and Dumber helped define an era of comedy in that was good to the Farrellys (who went on to successes like There's Something About Mary), and even better for the then-ubiquitous Carrey: In 1994 alone, he could be seen in Dumb and Dumber, Ace Ventura: Pet Detective, and The Mask; soon after, he delivered in films like The Cable Guy and The Truman Show. Now the gang's back with Dumb and Dumber To, and all that old glory seems like a very long time ago.

To be fair, Dumb and Dumber To is not terrible: Lloyd (Carrey) and Harry (Daniels) are the same old morons, and the plot follows in many of the same footsteps as the original, with the duo embarking on a road trip to find a girl, Penny (Rachel Melvin), while unwittingly being pursued by criminals Travis (Rob Riggle) and Adele (Laurie Holden).

The plot of To, though, is scarcely worth dwelling on—a flimsy construction of Elmer's and duct tape whose only real function is to be a conduit for the film's endless series of dumb jokes. Some of those jokes are lazy, and some of them are racial or otherwise un-PC, and only a few of them really land with impact—usually thanks to the full-bodied commitment of Carrey.

As a silly way to spend a couple hours, To will pass the time just fine, but only fine. There's little to make it feel new (an unrecognizable Bill Murray making a cameo that references Breaking Bad?) or bring anything into today's game that's a fraction as fun as what Dumb brought to the mid-'90s. It's nostalgic, and harmless, and will wash over you with numb passivity, but it can't top its predecessor. Dumb and Dumber To might be dumber, but it's not as funny.
