Not willing to pay when I can wait exactly one week and see it for free on Hulu or at Fox online. That's the big problem. I've thought about iTunes because I'd love to just have them all on my iPad, but it's not worth it because I'll eventually get the DVDs, you know? So I'd pay for 'em all twice. But I'll want to have them to watch all of the time.
(Or I'll watch them on netflix, which is what I currently do.)
