"Would you join a religious sect led by Peter Fonda?" So asked an exasperated Janet Maslin in 1982. A reasonable reservation on its face, until you recall all those other, actual, little more explicably appealing cult leaders (slash founders of religions, leaders of the free world, etc). Anyway, I found Fonda's feathery languor an apt marker of post-countercult quease. If the film's a bit lame, its dilemmas are real.
