Batman long Halloween part one is a very faithful adaptation from the comics. The movie did an amazing job establishing this world and characters Batman, Harvey Dent and the Joker. Jensen ackles was amazing as this younger not so experienced Batman along with other briliant voice cast. What works best in this movie is the holiday killer itself the mystery of that character will keep you thinking more once the movie is over. Also Dc animation was good too. Can't wait for part the two.
