This is a cheap and silly,self-indulgent gem. As far as there being a plausible story here,that is up to the viewer to decide,but to me much of it seems off-balanced and odd,stilted,forced,etc
...nobody behaves like some of these folks do,it simply doesn't ring true or hold itself together. BUT
If you simply watch this film for entertainment,and don't give it more thought than it needs,you will indeed enjoy yourself and have several good laughs ! Great rainy-day curiosity.
