the scene of batman spassing out from the poisen was indeed odd, to the point where i started to giggle at its pure silliness. i mean showing batman in the back seat of a car spassing with alfred driving him home reminded me of a kid who got hurt in school. i half expected bale to put his thumb in his mouth and go WAA!
what they could have done was either do the scene differently OR, IMO, ditch the scene altogether. they show batman on the rooftop all drugged up calling alfred on the phone and then cut to bruce waking up in bed. i think cutting that scene completely would have been best because it turned the scene from being kinda emotional to "what the.....LOL".
