IMHO, interesting/dynamic camera angles are not really necessary when the animation is fluid and lacks stiffness that needs to be "concealed" with flashiness. But I suppose we'll have to agree to disagree on that one.
But Ash's strategy involved more than just dodging in this case. He perfectly timed the dodge so that not only would Rowlet (and its load Rockruff) avoid getting Continental Crushed, but the boulder would also destroy the Stealth Rocks. Kiawe actually commented on how that was Ash's plan.
I went back to watch it and I don't see the need for timing. Lycanroc throws the giant rock then they just hover there for a while. They could have easily dodged without having to wait. I will give credit for ensuring that Rowlet was at the right spot for it to happen, but it wasn't a timing strategy.
Even then, it just shows how easy you can avoid them. Them waiting til it's pretty close to hit and still being able to dodge just means that they could have easily dodged any time before with 0 risk. Still depowering the z-move
