Weak plot, useless scenes, and some of the most repulsive closeups in film - Cloris Leachman singing & farting, smoking cigarettes, and talking with her mouth full, grandpa pulling his dentures out & licking them, rancid peanut butter on a stale cracker, fresh cow flop, and filthy toilets. Then there's the inbred-looking, mentally impaired in-laws (one with a hideous deformity}, a crazed halfwit farm hand, and VW bus full of dirty hippies. Most of the people in this film look like they haven't bathed or showered for months. You can almost smell them.
