I mean
the production quality was fine. really good
They mostly maintained a single algorithm, which keeps it simple. They could have used (Right sexy, Left sexy, Right inverse, Left Inverse) instead of sune for edge permutation, and (z2 sexy D inverse D' etc) instead of niklas for corner permutation. Otherwise, they kept to one algorithm pretty well.
My biggest problem with this tutorial was the complete lack of trouble shooting. People get really caught up on flipped edges in place and F2L pieces swapped around. This definitely should have been addressed.
Otherwise it was a great tutorial. I don't get what problems you guys are seeing that make you say it's so bad. Yes, he says "R apostrophe" instead of "R prime" but that's hardly a real issue.
Also, I watched the video on 1.75 speed, so if he was talking slowly, then I didn't catch that.
