Well, if nothing else, they got the name right. This is an immensely stupid movie. Not that its progenitor, “Dumb and Dumber,” wasn't a stupid movie too. It was a highly stupid movie, but it had the benefit of being funny between bouts of stupidity, if not actually during them. “Dumb and Dumberer,” on the other hand, is only stupid. The first film also starred Jim Carrey and Jeff Daniels, an odd pairing that, by some weird organic process, worked. “Dumb and Dumberer” stars a couple of Jim Carrey and Jeff Daniels knock-offs: Eric Christian Olsen (“The Hot Chick”) as dumb, and Derek Richardson (TV's “Felicity”) as dumberer. They are effectively doing impressions of Carrey's Lloyd and Daniels' Harry, respectively. Which couldn't be less funny or more pointless. This isn't to say they aren't doing great imitations--they are, in fact, dead-on--but who needs them?

As for the film, it takes place in 1986 during Lloyd and Harry's high school years. They get caught up in some scheme the principal (Eugene Levy) and the Lunch Lady (Cheri Oteri) devise to bilk the district out of a lot of money by pretending to have a class of ‘special needs' students--of which Lloyd and Harry are the mascots. Not a moment of it is anything other than the filler between bits--several of which are lifted directly from the original film. Particularly, there is the excrement motif that the films share. Here, it's also an apt description of the movie itself. Starring Eric Christian Olsen, Derek Richardson, Rachel Nichols, Cheri Oteri, Luis Guzman, Mimi Rogers and Eugene Levy.
