"Tron: Legacy" is one of those movies that makes you stop and seriously wonder whether there isn't some kind of Stupid Test you have to pass in order to be allowed to work at a studio these days.

I mean, what sort of producer looks at a film that was an under-performing disappointment and critical failure 30 years ago — as was "Tron" — and then says, "Hey, great idea! Let's do a sequel! And while we're at it, let's throw $150-200 million at it — it'll be great!"

In gambling, this is known as "doubling down," and far more often than not, it doesn't end well; you walk away deeper in the hole and with a couple of scary-looking guys named Vinnie threatening to break your knees. Mickey must be double-locking the doors at the Magic Kingdom this month after a weak opening for "Tron: Legacy" at the box office.
