Wait, so if the cabin was destroyed in the 80's, why did it make no difference when Ash got back to the present? Furthermore, how the hell did they get back to the present?

I fully bought into Chris' exploitation of her daughter ever since Regan mentioned it. There isn't an actress alive (especially an aging one) who wouldn't use that to keep herself in the limelight after the media circus descends. Hell, I'm shocked she didn't try to book her daughter at Fangoria conventions.
