Score

A+

Truly outstanding. The sort of film that makes you ask "Oh my god, how did I live before seeing this film?"

A

Must see. Definitely one for the DVD collection. Highly recommended.

B

Entertaining. Good for comedy/entertainment value, worth seeing. Possible contender for the DVD collection.

C

Average. Not a great film, but not terrible either.

D

A bad film. Bad script/acting, implausible plot or huge gaping plot holes.

E

Failed to meet even basic entertainment value, not worth seeing.

F

So bad that it makes me feel I've just wasted two hours of my life.
