Its been years since I last saw the film, but it is all good fun as I remember it. It isn't a splatterfilm or anything, more like a macabre musical. If my memory serves me right, I can't se a reason why you shouldn't watch it. The grown up themes and such are mostly sexual (or parodic or whatever). Although not a children's movie (kids might not "get" it), I have never thought it unsuited for children - am I wrong? (Besides transvestite Frank, I do not remember it very well)
