What's the point of this small gem?
It's about Leon (getting to know to) being somewhat different, based on his ancestry in contrast to the environment and society he lives, just because of some information, that doesn't necessarily need to influence his life, but still manages to push him into a process of self discovery.
While the first half shows Leons life as a modern jew, maybe comparable to how "The Nanny" did, later on. This culture gives the movie some known, solid background, but the story could get transposed to combinations of cultures and societies, without losing its statement.
Leons real struggle turns around his two lovers: one girl dreaming of an exciting partner and therefore not willing to commit to him, another one, that just loves to scandalize in her art and her loving.
The second half comes up with the absurd twist of the (impossible) hybrid being (which is never shown), making it a kind of allegory for Leon and starting some discussions, where british comedies do excel.
Apart from Conny Booth (Fawlty Towers!), Maryam D'Abo (fresh from the Bond) and (the then lesser known?) Gina Bellman the cast bears no big names, but overall matching, sympathetic acting. The pace of the story runs smooth.
I give it a 7, because it proves decent movie can be made with minimum fundings.
