There’s good bad and bad bad, sometimes which category a movie falls into is very mood and context based. Off the top of my head, Sound of Freedom was bad in a not enjoyable way, although I enjoyed podcasts discussing it.

There’s also “incredulously bad”, which are movies/shows that are terrible but have good ratings and reviews. Like you can’t understand why they’re generally considered good. West Wing is probably a good example of a show in this category.

One problem is arguably the worst thing a film can do is be forgettable, so I probably don’t even remember the worst ones I’ve seen.
