Given that the Okudas and Dan Curry were involved in the remastering of S2, I'm surprised they were content with what HTV was churning out. How involved were they though? You'd think with them looking over the project, especially Dan Curry, that the effects would at least be more than "acceptable".
A lot of times having someone so close to the project managing it actually damages the final product, rather than help it. I'm not saying that's the case here, but I recall when S2 first came out a lot of people were saying that many of the flaws were a tell of Dan Curry's involvement. He and Lagato had two distinct styles when it came the the SFX, but with Curry's involvement in the remaster, his style began to bleed into Lagato's episodes. That was the claim when the season came out, as to whether it's true or not is anyone's guess.
