It was the funniest thing. I was watching G.I. Joe: Retaliation, wondering how I hadn’t gotten around to watching it since I found the first entertaining in a goofy way. Then that deja vu feeling starts as I watching and I realize I had seen it - and yet it made so little impression I didn’t remember seeing it. In fact, I was having trouble remembering details even as it played along in front of me.
I’ve had this happen with books - remember 50 pages in that I’d read it before - but never with a movie.
