Hold on a sec, you don’t want them to use any of the Highlander 2 revolutionary ideas?

Seriously though, trying to reboot Highlander might actually work. It’s a known property, but really only the first movie had any value (and some of the TV series) and it’s not that well known from younger generations. It’s also not such a classic that you cannot touch it without people screaming (like, say, Ghostbusters)
