tbh, I find john Wayne's acting tedious
For the most part I agree. His character was always the same, even though he did a great job with that character. Clint Eastwood is pretty much the same way. They make great gritty tough guys, whether they're a cowboy, a cop, or a soldier. But I can't really see them as anything else. To be a "great actor," they have to be able to cross over many genres and types of characters.
