Netflix sucks big time it has old movies and they don't even have the lion king for my kids to Watch. I had Netflix for free with the promotion that they offer I called back the third day and cancell that mess. (Netflix Sucks)
You won't find Disney films on demand anywhere - they don't believe in it. Hence their movies come out once every couple of years with 3 more features for full price - greed.
As for it's cost, it's £6 a month so it's the same price as renting a ONE HD movie from iTunes.
My daughter watches loads of the kids stuff, I watch lots of TV shows and the odd movie and it costs £1.50 a week... Why are you complaining?
