Every time I think "hey I wanna watch that one movie again" it's never on any of the streaming services I pay for. Even old ass movies like the godfather are missing and I'm asked to instead rent them. Fuck you, where's my pirate flag??
I recommend the app “Just Watch”. Pump in whatever you wanna watch and it’ll tell you what services it’s available to stream on. If none, hoist the flag, amigo!
Just want to mention that this issue is even worse for content from non-US markets.
There's a huge list of classics from where I live that are completely impossible to find and we depend on one privately owned platform to decide to buy the rights and make it available even if these productions received public financing and that's just when it's clear who owns the rights.
Yeah it's also worse for streaming outside US markets, especially if you prefer original English. Supposedly you can use VPN but that didn't work plus you need credit card.
