For MEL, I dug into a recent cinematic phenomenon. We're used to prequels, remakes and reboots, but what about the way-too-late sequel? I'm talking about films like Zoolander 2 and My Big Fat Greek Wedding 2: follow-up films that come out way, way, way after anyone would have reasonably expected a sequel. More such sequels are on their way this year. What's the deal? Read my take.
