MY GOD, what a load of old codswallop!!!
I'm not being funny but I'm convinced the people who gave this a positive response must've been watching something totally different. Also I found it very odd that every couple in the movie is a mixed (b&w) couple. Like...after the first few times it became quite eery.
Having said that I would say give it a watch as I and my sister were rolling on the floor laughing for most of it (at the ridiculousness, not because it's a comedy).

Urgh.
