is nobody going to mention "Enemy Mine" ? Only one of the best sci fi movies from the 80's! That's one I would certainly hate to see remade.
Watched the 2015 Z for Zachariah yesterday and wasn't all too impressed. I found the setting interesting, and wanted to know more about that, and the backstory of the characters. It seemed like there could have been a rich backstory to the whole thing which I guess you only get from the book (haven't read). But I agree with Dewi, it just felt like it was all about who was going to win out with the lass which just ruined it for me.
