As well as being a delight to watch, the quality of sound and picture is excellent.

The extras, however, are underwhelming. You have the obligatory chapter and language selections, which might appeal to a Spanish waiter with a short attention span. Otherwise, forget it.

The star attraction is what they call "the theatrical trailer." If, like me, you hate trailers - they give away the best parts and murder subtlety - this is no fun at all.

Final judgement: movie a must, extras a must not.
