It'd be great if it didn't take ages to load and was poor quality (which it generally is). I remember watching Days of Heaven on my computer, so strawberry floating bad. I wanted to watch Oldboy, ended up just using a website to stream it, much better quality. Bit of a shame really, but a great service for actually renting DVDs and games I think.
Perhaps my eyes are bad, but I think the picture quality is fine. I just have an ordinary flat-screen TV and it comes up as pretty much DVD quality, except in some dark areas you can tell it's a bit 'blocky'.
I spent so long trying to choose a film from the vast on-screen database last night that I fell asleep before making my decision.
I notice The Hurt Locker is up there this week so that's tonight sorted
