After you nab Despicable Me for the kiddos, those of us who saw the original back in the day in the actual theater (after, of course, falling in love with Michael J. Fox a little while watching him on Family Ties on TV) may want to grab this Back to the Future Trilogy Anniversary Edition at Amazon, also for just $15. This one has all three movies on Blu-ray, plus all kinds of bonus features, and then digital copies of everything as well. And it has free shipping, even if it’s the only thing you buy.
I suspect if I made my kids watch it, they’d complain it was “lame,” but what do they know? This was one of my favorite movies back when I was a kid and dinosaurs still roamed the streets.
