I saw Willard today. I enjoyed it, to an extent. I've never seen the original, but enjoyed this new incarnation on its own, amusing and creepy. And yes, the theme from Ben appears, twice: The Jackson Five original, and Crispin Glover's rendition. Reminded me a bit of Office Killer, as well as Glover's recent piece of garbage, Bartleby. If you aren't sure if you want to see this or not, I'd go with your gut, but if, like me, you find yourself inexplicably reconsidering your initial reaction of "Why the hell are they remaking Willard?," I'd say go with your instincts.
