Plot Hole

Wasn't it one of those deals where light is bent around the suit so you see what is behind the wearer?

Current invisibility tech is predicated on a mosaic of screen/cameras that project the visible field to your rear through the screens in front - so you wouldn't "block" out the view. I was wondering about the power source, seemed almost as inexhaustible as the camera lights in The Blair Witch Projecct.
