The writer, Kevin Fox, is best known for The Negotiator, which is a movie I’ve watched more times than I can reasonably hope to justify. And this is just an excellent script – it’s complicated and engrossing. He balances a lot of characters and gives us a reason to care about them, even if those characters don’t actually know why that is. Their relationships are fascinating, as every time somebody is reset, the other characters have to help them rebuild the personality that they remember. The main characters are collections of their own instincts, held together with the pieces of information that other people can tell them about themselves. We’ve seen stories of amnesiacs before, but this is five amnesiacs trying to work as a collective and also occasionally losing all of their progress. That’s a tricky path to take, and Fox handles it beautifully.
