Interesting comparison of users' experiences with Greencine versus Netflix. Many positive Netflix comments.
The primary difference I see is that Greencine apparently buys their DVDs off the shelf, so they can't afford as many copies, which allows for great diversity but low availability. However, Netflix has revenue-sharing agreements for their inventory, so they can make as many copies as they need.
I say Netflix is NOT a "monolith" as one user put it. It was itself a startup not so long ago. I do not fault it for its success nor favor Greencine for being "the little guy". They both have profit as their main motive, or else they wouldn't be charging, now would they?
