OMG! haha. There are no words to adequately describe how really bad this movie is. I gave it a 3 rating only because it's so much darned fun to goof on. The acting is third rate; the story is second rate; and everything else goes downhill from there. Even the dancers who are supposedly dancing the Frug, the Swim, and other 1965 period dancers are bad.
The oddest element is the incidental music played while people are talking. It's impossible to describe! I guess it was meant to be funny — a la Ozzie & Harriet, perhaps, but it's just so bad and has no real connection to the scenes in which it is played.
Sonny & Cher's performance is typical, but the song, "It's Gonna Rain Outside" is laughable.
This would have been perfect for the old 80s show MST3000, which goofed on bottom-budget movies like this. These days it's probably best for stoners who may or may not recall 1965.
