Watched it last night and I agree with the voice comment....That voice was the perfect Batman voice..when he didn't talk much. When he has that much dialogue, it starts to sound funny and you stop listening and start trying to figure out why he sounds like that.
And here's what I came up with. 1)the mask prevents him from breathing through his nose so his pronounciation becomes a little nasal. 2) he keeps his teeth separated and rarely moves his jaw. The result is all the words are formed from heavy exhalation and lip movement alone so he drops letters all over the place like a ventrilequist. It becomes more obvious the more he talks.
