The key for me is that I need the acting to also be “bad” via either being unintentionally funny from an actor trying to hard (Nuclear Man’s actor, Mark Wahlberg, Nick Cage) or intentionally funny from an actor who knows what type of movie they’re in (Gene Hackman.)
The last thing a bad film needs is for the actor’s to actually perfectly hit the exact type of performance the director wants, and wind up just highlighting how bad the directors vision is - like in The Last a Jedi, where *everyone’s* much better than the material they’re given, so you just find yourself hating the film instead because you can tell the director is genuinely hurting the performance just as much as the story. Like, we can all tell that Mark Hamil *could* do a great Broken!Luke story… but instead he’s stuck doing a boringly self-centered coward instead.
