As the most wonderful time of the year approaches, everyone is settling down to watch Christmas movies. There’s plenty on offer whether you want a cozy classic, a cheesy Hallmark guilty pleasure, or some alternative horror festive offerings (I’m usually the latter, admittedly). The best streaming serviceshave a lot on offer, but the Roku Channel has announced a very different kind of movie, one that might end up costing you more than you planned.
