I’m not sure which package I’m on, but I get HD and it’s about a fiver a month – it’s very very good value compared to Sky for example.
As someone else said, check your download limits from your ISP or you might find it gets very expensive – unlimited it best.
HD works fine for me even with my crappy 4.5mg download via my PC, but it’s appalling via my PS3.
As for the service, most films are older, crap or both – there are some gems in there, but you have to wade through a lot of straight to DVD stuff – but their exclusive TV stuff is great – Breaking Bad, Better call Saul, Orange is the new Black, House of Cards – intelligent, well made stuff and if you’re into it, it seems there’s a least a chance that NotGear with Jeremy Clarkson and the other two with be on Netflix.
If you want more, you can use something like Hola to trick your PC into thinking it’s in the US or Canada – Netflix has one international account, but content differs from country to country – Canada gets the best films.
