If you want quality you should pay for it.
A lot products are sold with both a high quality and a cheaper low quality version. Mobile phones, televisions, headphones, you name it. For a better quality movie, you can buy blue-ray.
I know that wether or not something is expensive is a matter of opinion, but I live in a country with extreme taxes and whatnot added to the price, and I don't find movies or music to be expensive. I find games to be expensive, but if you choose wisely you get many hours of fun.
