Just had a read of your article Simon! I'm in total agreement with you that nothing beats the cinema experience, it really is its own kind of magic.
I'm not sure I buy into your counterargument though. You're saying because not everyone can afford a home entertainment system they're not a viable alternative - my point is that a lot of people can afford neither. Most people have a smartphone though, so the price of a Netflix subscription wins out there. I get that it's not the 'true' cinema experience, but this is exactly my criticism of the kind of anti-Netflix gatekeeping that crops up in the cinematic community. You shouldn't be excluded from enjoying a piece of art just because you can't afford to see it in IMAX - no matter what Christopher Nolan might think. The beauty of art is being able to enjoy it however you can.
To your point about the content rights control as mentioned by the other commenters, I concede that this is something I need to take into account more regarding how I feel about streaming services. I've been a personal victim - my favourite episode of Community was pulled by Netflix because of this! I guess because I know I can find an illegal Community streaming site in a matter of seconds, it's not something that's bothered me - but that's a slippery slope, especially when talking about the ethical place of streaming services in society.
Thanks for your comment, I appreciate it!
