I can't speak to Hamlet as I also haven't seen it but yes I think it does count from what I know of it.

I think its just a real damned if you do or don't situation. Because without the exposition you will end up with a lot of things just looking pulled out of your ass or just not making sense, ruining big moments and underlying tensions.

Its why books are usually considered a "superior" form of entertainment, because its the only place you can exposit without anyone really saying anything or an awkward narrator doing it for you. Which makes it even more hilarious and a red flag when hack writers don't realize that and have characters explain things out loud in story.
