Oh there was dialogue in BEGINS. I find it funny people get upset at it's to the point nature, and shrug it off as being less intelligent. They truly don't know what they're talking about. The movie was to be epic in scope. The ideas from the character and the story is VERY idealistic. So therefore the dialogue follows suit. It was supposed to be that way.
It's funny, people who don't understand Nolan's vastly superior movie, or who flat out ride Burton's jock shrug things off like the dialogue as being simple or stupid as a means to discredit the film. "No subtelty" is commonly used. The film Batman Begins was MEANT ... to be idealistic, broad in scope, thematic ... and yes, was supposed to show the detail of the origin of this character. That hardly makes a movie less intelligent. Batman Begins was the MOST intelligent film of the bunch.
Burton homers love that no subtely jab. Yes, B89 and Returns are very "subtle" in dialogue. While at the same time not saying ANYTHING w/ or w/o that subtle dialogue. Batman Begins makes STATEMENTS. Both philisophically and sociologically in their film.
Batman Begins is subtle and somber in it's looks, and is bombastic and meaningful in it's characterization, story, the world created, it's themes, and it's dialogue.
Burton's Batman movies are bombastic and superficial in looks ... and ultimately don't amount to anything intelligent, because the actual story / dialogue doesn't say or do anything with the characters. They have no meaning what so ever.
Batman Begins gutter looks and broad and powerful story is a powerful device and view point borrowed from the BEST source material of Batman.
