Just to throw my two pence worth in ( or $8 dollars, depending on the current exchange rate).
I thought this and the previous Batman are the two films we've been waiting for.
The original t.v series for all it's camp comic book fun was just that, over the top and rightly owned it's place in television history.
Tim Burton's version turned down the colour contrast of Gotham with it's brooding skylines and menacing streets that once haunted cities like New York he insured the character of Batman had some real edge, a life and emotion- but it still managed to keep the child friendly 'virtual' laughter track intact for the kids.
Christopher Nolan's bypasses and in my opinion surpasses all of the above. Taking the genre back to the Batman you saw on the cover of comic magazines and wondered ..where's that 'Zap' and 'Ka-Pow' bubble and why is he so big and scary?! He's not like that nice Batman you see at the cinema
This Batman is for the adults. Heath's Joker was akin to some one you would never want to be left alone with as a child. Unlike Uncle Jack as the previous incarnation of the Joker who did look he'd have a flower that sprayed water - Ledger's would spin and decapitate you!
Once the Joker appears and he systematically assassinates each and one of his bank heist accomplices - you know this is not going to be a Disney film for kids.
So Pros and cons of Dark Knight-
Pros: Batman can be just as evil and menacing as any one of his assailants, just ask Joker when he's in Police custody! Ledger's Joker helps erase all the memories of Jerry Hall and they got rid of Katie Holmes!
Cons: It's twenty minutes too long!
OH while I'm here please avoid Starship Troopers 3 - It's beyond
dreadful !!
Some one arrest Mary-Kate Olson , she's definitely helping in the hiding of the truth behind Heath Ledger's death in NYC. The Whore
