If you’ve burned out all the MST3K options on Netflix (and YouTube), then there’s only one alternative: RiffTrax. Their new player basically combines their riff (normally $4, but just pretend you’re purchasing an episode of MST) and your DVD—not in a magical sense, but if you happened to pick up The Happening for a dollar like I did, you finally have incentive to watch it.
All for a $5 well-spent.
And it’s a free download that gets you one free Riff.
