TV and/or Movie Recs?

I'm browsing around for things to watch, and I wouldn't mind some recs? I'm looking for:

- Old TV series, meaning ones that are already completed or as completed as they're going to get. Anything you think I might enjoy.

- Black & White movies. I've got a craving, and I want to broaden my film experiences. I'm particularly interested in old horror or thriller movies.

Anything spring to mind?
