"Hate" might be a strong word. Maybe I'll go with "despise".
I think his videos are quite good.
That totally depends on what you're looking for, I guess. His "live commentaries" are mostly him playing much weaker opponents (if that's not the case, how come he won like 99% of his live commented games? And the ones he lost (like that one against a KGS 1k) magically don't appear on youtube) and his "pro reviews" lack a lot in useful discussion, imho.
It seems to be just him speed-clicking through pro games, which I could do by myself. (His commentary on pro games doesn't ever seem to exceed KGS 5k level.)
I was even inspired by one of his videos that I can't seem to find at the moment where he reviewed a series of games betweeen a pro and amateur on Tygem where the amateur player starts at tengen and when white plays 4-4 immediately invades at 3-3. While Batt doesn't seem too fond of the amateur's play, I've tried that same strategy a couple of times as a result because I think it's an interesting idea.
The video you're referring to is a good example, actually. What is there to comment? Some amateur plays a *really* bad opening against someone who is *much* stronger than him, and gets destroyed. Do we really need to stretch that into 1 hour and 4 minutes?
Also I really dislike how arrogant he sometimes gets while playing much weaker opponents on camera. ("I'll let him get away with that" is the sort of comment I mean. If you have to "let him get away with that", maybe you shouldn't be playing someone *this* weak in the first place. Or sometimes he'll say "I'll be nice", when his weaker opponent is obviously struggling. It's just arrogant, imho. You could make those comments in even games, perhaps, but not when your opponent is >=2 stones weaker.)
All that said, I actually enjoyed a lot of Bat's videos for their entertainment value (including the video you mentioned).
I guess I just don't like that he tries to pawn it off as him teaching. If he'd call his youtube channel "The go clown show!" (forgetting about all the non-go stuff on there for the moment), I wouldn't have any negative feelings towards him what's-o-ever.
