This is terrible. I mean, I'm a fan of "good" bad movies, but this is a "bad" bad movie. It has absolutely nothing to recommend it. It fails the first rule of comedies, which is "It must be funny". This isn't even unintentionally funny. The entire cast must be spending their time denying they were ever in it. I stromgly suspect the directors and writers were consuming far too many illegal substances during the whole affair.
Pros: the plot actually isn't a bad concept. The cast includes good people who do their best but the whole thing is completely inadequate to their talents.
Cons: It's crap. The characters are unconvincing. The writing is terrible. As "comedies" go, you'd laugh more at somebody strangling kittens. The whole thing feels like it's been conceived as an effort for the directors to go back to their drug-addled 1960's memories.
Conclusion: avoid at all costs.
