What annoying continuity? Apart from the whole Robin thing and Jack Napier killing the Waynes? Besides, "Begins" is nto really faithful to the comics as well...
**** SPOILERS AHEAD *** The movie ended with an open possibility for a sequel, staring... the Joker. Hmn, I don't think anyone can play the Joker as good as Jack Nicholson did in "Batman", so I hope this was just a reference.
