Go to your local library. Many have a great selection on blu-ray and dvds. Having to select something from a shelf is way more enjoyable than the endless scroll of junk streaming services give you. I am now actually purposefully selecting movies and shows to watch and making time and effort to finish them instead of just streaming random stuff.

Plus you get commentaries and bonus features.

Can also just do that by having a backlog of good films. Something like ‘Roger Ebert’s list of great movies’, for starters. As a bonus, the list has many films from outside Hollywood.
