Oldboy seems to be a love it or hate it kind of show, from what I've read. People don't seem to say "eh, it was OK."
Oh, forgot to say I watched Yes Man on the plane this weekend. It wasn't the worst thing I've ever watched, but I did think he bought into the saying yes to everything covenant junk way too easily. Maybe I'm underestimating the power of peer pressure, but I'm thinking many folks would have said yes in the meeting in front of everyone, then not actually done anything.
Of course, that'd make a pretty crappy movie: "No Man Who Buckled for Five Seconds in Front of a Huge Crowd of Strangers." :)
