It takes a certain kind of brilliance to make a great dumb comedy, and the Farrelly Brothers used to be among the best.

It takes a certain kind of brilliance to make a great dumb comedy, and the Farrelly Brothers used to be among the best.

Their first three films ("Dumb & Dumber," "Kingpin," "There's Something About Mary") were like catching stupid lighting in a bottle three times in a row. Their films since then have been steady skidmark on the underpants of their career.

But 20 years after "Dumb & Dumber," they've gotten the band back together, and dammit if I wasn't a little more excited than I should have been, particularly at the opportunity to see Jeff Daniels out-silly Jim Carrey. (Do more comedies, Jeff.)

The copyeditor in me even LOLed at the grammar joke in the title. I was settled in for a good, dumb time. It wasn't to be.

The whereabouts of Harry (Daniels) and Lloyd (Carrey) for the past two decades are revealed in an opening gag that is a) one of the movie's funnier moments and b) already ruined if you've seen the trailer.

A basic premise is set up to prop up the inevitable gags. Harry and Lloyd head across the country in search of Harry's newly discovered daughter (Rachel Melvin), who was given up for adoption by her mother two decades prior.

As I sat through this movie and managed only a few good laughs, I realized that Bobby and Peter Farrelly are, like Frankenstein, victims of a monster of their own creation. The silly and lowbrow humor they brought to the forefront was often imitated (even later by themselves), and it grew pretty stale even before it went into hibernation.

Carrey and Daniels still throw themselves full speed ahead into the silliness, as does Melvin playing to the ditz trope (can't wait to see her in next year's "Zombeavers").

But the material just isn't that funny. The nonstop nonsense one can see on YouTube has numbed us to pratfalls.

There are probably just enough laughs if you're a superfan of the first movie, but it's a pretty limp sequel.

As if proof that the timing of "Dumb and Dumber To" is off, a cameo by Jennifer Lawrence was cut from the film (possibly at the request of the actress), but a spot by "Honey Boo Boo" mom Mama June remains.
