Well, my words might have been overly harsh, but I have high expectations of this show, for a good reason, so it's no altogether unjustified.
Plus I know you aren't in reality as stupid as saying "I don't want to look at a black screen for 10 minutes" sounds like. As if that was the only alternative to this episode where there wasn't a single spec of darkness at all. Just a few scenes from Gon's low perspective would have been enough to create a really nice effect of an enemy appearing out of nowhere and then disappearing again before he had a chance to react.
