I have Shudder but I don't ever watch anything on it. Though, I'll admit I like being able to turn on the TV function and just drop into whatever they're playing. I'll do that sometimes when I can't decide what to watch
You should give The Last Drive-In a try sometime! It's currently mid-season and they're on a hiatus until the end of June, but most of their old episodes are still up on Shudder. They only take episodes down if Shudder ever loses streaming rights for a particular movie.
