I liked the use of tech in this film but let me state right now I didn't like the joker. Not that he was a bad villain. It was that he was not the joker from my childhood. I understand that they were trying to shock audience this sick twisted version of the Joker. I just didn't like Ledgers version of him. Yes when it came to crazy he pulled off crazy like most have never seen, but I feel he was a new villian all his own. Aside from my personal childhood likings I found this film to be an excellent source for entertainment. The plot was well thought out with great shocks and thrillers in it. They mixed live action with CGI perfectly. I don't feel they did a great job of turning Harvey to TwoFace. So overall the film was worth seeing and buying.
