I'd love to see a remake of Battle Royale 2.
The basic concept was a genius idea for a sequel (past survivors of Battle Royales form a terrorist group to take down the people responsible for the BR Act) but a mixture of the original director's ill health, his son having to take over when he passed away, a patchy script and some awful actors really messed it up.
I've written a comic! It's really good - promise! Check it out HERE
