The Dark Knight is an extraordinary mish-mash lacking logic and cohesion.

Technically, the film is well made. That is, it looks and feels like a blockbuster, though a solid score is sorely lacking.

On the plus side, Michael Caine and Gary Oldman add gravitas to an otherwise ordinary ensemble.

And sadly, a fine actor will be remembered, not for the likes of moving and sensitive performances seen in Brokeback Mountain and Candy, but rather an excellent make-up job, an over-active tongue and a silly voice. As farewell performances rate, Heath Ledger's Joker sits alongside Peter Sellers' Fiendish Plot of Dr Fu Manchu.

To remind yourself how super hero movies should be made, dust off your copy of Spiderman II (from which it borrows) or Superman The Movie (from which it should've borrowed).
