I didn't say anything about visuals. I said "action scenes". Even so, I'll admit I overstated my case a little bit.

A movie that is all action, though, is just boring. An action scene should be there to heighten the emotion that the audience is feeling. If it's all action, then you can't heighten it. It's like audio level compression. If it's all loud, why bother?

That's not to say that there isn't a place for an all-action movie, but it feels like that's all that comes out any more. (Also hyperbole.)
