All the Star Wars films and series are there. I also recommend The Mandalorian which is not just excellent and loads of fun, but restored my faith in Star Wars so much that we started watching Clone Wars and Rebels (lots better than expected) and can't wait for The Mandalorian's return and its spin-offs.

I've also been catching up on the whole Marvel film canon in chronological order (must get back to that) and often come across films I loved as a kid. The original Parent Trap came up one day and we watched it - it was still great, and Greg was impressed too. I don't know if you like animated films, but all of the Pixar films are there too.
