Unoriginal original movie

Rating: 4/10 (10 February 2008)

Derivative rip-off of "National Lampoon's Vacation" -- uh, let's see, how about we have a dysfunctional family driving across the country together and a relative traveling with them dies on the way. Or, how about we have one of the kids not talking to the family the whole movie -- uh, wasn't that done in "The Royal Tenenbaums." The parents are good, Alan Arkin plays another in his long chain of annoying characters and I don't think a character spouting off obscenities throughout a movie is particularly humorous.
LMS has some cute moments, but the rip-offs from other movies, the obscene grandpa, and the trashy ending made this a big disappointment.
