Yeah, my main motivation in setting up Jellyfin was to have everything in one place.
No more having to check which service has it, only to find that 20 year old movie can only be rented for £6.99.
I'd probably pay the cost of 2 streaming services, in order to have a single service that has literally everything on it, and keeps it on it.

He's bad in those movies, but I don't think it fixes them. Not by a long shot.
