Even from their distance, Itachi was looking at Sasuke, so he could still make out his shape. So even if it was just a blob, he can see the blob's movement if it's as drastic as raising your arm above your head then swinging it all the way down.

Nothing indicates it was dark out. It was just cloudy. Plus Lightning crackled before the tech hit so we know Itachi saw some brightness before Sasuke attacked as well.

Yeah, Itachi had to have impressive reactions to get the timing right. But he pretty much knew exactly when it was coming, so it's not as impressive as you want it to be.

It's a reaction and predictive feat at best, not even a travel feat.

I never forgot Zetsu's comments. I even made mention of the fact that Itachi was sick in an above comment. I'm not super impressed with it because Itachi was always noted to be above Kakashi even while sick. So the fact that sick Itachi managed to do something that Kid Kakashi at full health could do isn't surprising because it's already established that Itachi is more formidable than Kakashi.

There's nothing saying that Lightning Release attracts Lightning Release. Kakashi just blocked the Lightning. Otherwise, Sasuke would be at risk of getting his because he had Chidori active when using Kirin and was higher than Itachi. Kakashi reacted to Lightning, plain and simple. And he didn't have Sasuke as an auditory and visual cue to get ready either. Yes he had full health and vision. But full health and vision Kakashi is already established to be below sick Itachi. So it's not surprising.

Again though, we're looking for travel speed. Not reaction time.
