It might not be clever, but Dumb and Dumber To looks like it could end up being a pretty big movie, after taking $14.2 million at the box office on its opening Friday. The comedy sequel is now predicted to earn between $30 and 35 million in the US over the following two days, just less than its $40 million budget.

Starring Jim Carrey and Jeff Daniels as the dimwitted Harry and Lloyd, the sequel comes 20 years after the original movie. Back in 1994 Dumb and Dumber had managed $16 million in its opening weekend, going on to gross more than $247 million worldwide.

This time around the two are older but certainly not wiser, as they go off on a road trip in search of Harry’s long lost daughter who was given up for adoption.

But while we hadn’t expected Harry and Lloyd to have grown up much, it seems their humour could have done with a little maturing. Critics have been quick to pan the sequel, comparing it unfavourably with its predecessor, it currently holds a 27% rating on Rotten Tomatoes.

Writing for the Associated Press Lindsey Bahr said, “what may have been subversive and irreverent in 1994, now just seems vulgar, hateful and tone-deaf.”

While Betsey Sharkey of the Los Angeles Times echoed her feelings in her review saying, "what felt fresh in Peter and Bobby Farrelly's original Dumb and Dumber, with the Carrey-Daniels dense duo channeling the Stooges and Jerry Lewis and something else entirely, feels strangely old-fashioned two decades later.”
