I, for one, would love to see a Highlander reimagining/reboot. I think the concept still has potential, but the franchise as it stands now is deader'n Brittney Spears' career.
However, there's one major caveat, at least for me. If the main character is going to be a Scottish highlander, than for God's sake, let him wield a claymore! No more of this "Oh, I got my katana from an Egyptian with a Spanish name and more of a Scottish accent than I have."
