Honestly, it's obvious you didn't even watch this wanting to enjoy it, you went in from the start already set on criticising it because of the actor and that's it. And that's not fair, because the work isn't just his, it's an entire cast and crew who put effort into this and aren't at fault for anything. Also, what we know about that news is just what came out publicly, nothing more. You don't actually know what happened behind closed doors, and the person in question has already passed away, he can't even give his side of the story. If he really did something wrong, that's on him, it's not your place to be his judge or take that anger out on an entire production. If you weren't going to watch it with an open mind, you might as well not have bothered. Watching something just to confirm to yourself that you weren't going to like it and then trashing it with a review like this isn't criticism, it's just venting. If you don't like it, don't watch it, but there's no need to come and damage the work of people who have nothing to do with it.
