From Row Three:
Note how they put the Canon 7D camera at odd angles and settings (From above as a body is dragged across the floor, into the water with the actors). You can't do that with a film camera without a lot of extra equipment and crew to help stage the shot. I'm looking at these and thinking ladder for one shot and a "dive bag" for the other.
This frees up the Director and DP (maybe the same person!) to concentrate on the creative aspect of things - working with the actors, staging shots, lighting, camera moves - the visual storytelling.
That, kids is the win.
