I am a fan of the original film starring Jim Carrey and Jeff Daniels and i enjoyed this film aswell. Obviously, Olsen and Richardson come no where near to the original duo but they did do a good job of..well..acting dumb i guess.
I mean this film is no classic like Dumb and Dumber but it was fun and entertaining, i do not agree with all of the negative comments of critics and fans because if you imagine this film came before the original movie i think everyone would react better to it.
Other Jim Carrey-less sequels like Son of The Mask were horrible i agree with that, The Mask is my favourite movie and after seeing it's terible sequel it has taken away all hope for another installment following the first, so i can understand why people are rating this low.
But this film wasnt as bad as everyone is making out, give it a try!
