but in terms of servicing the movie, i mean, does it do anything? it just seems pointless mostly (plus it makes everything dimmer, which i find annoying)

i think its a technology that has to be used in a gimmicky (and this can be fun) rather than trying to make it seem like some great new leap in filmmaking

ie it made sense in piranha 3d cos it was like the fish were coming at my head and about to eat my face lol
