I can name several that are worse than many of the anime on his list.
Guyver: Out of Control (1986) -- Dub or sub, the story deviates so much from the Guyver storyline...in a bad way. It has very awkward pacing, characters appear out of nowhere with no background as to why they exist, and is filled with more fan service than plot. Gives the manga a bad name.
Ghost Stories (2000-2001; Original Sub) -- The dialogue was such garbage that ADV ended up writing their own crazy dialogue for this series when they still had the rights to distribute it in North America. I've seen both. The crazy English dub is superior...
Phantasy Star Online 2: The Animation (2016) -- Most of the anime resembles a high school comedy, instead of the fucking game it was supposed to be based on. That didn't sit well with me. Granted, I dropped it after the first two episodes and found this out later. Its reception is mixed, but the negativity from would-be fans can be described as volatile.
Baoh (1989) -- Gonna' be honest, it probably wouldn't go with this guy's list because it's that "good" kind of bad. So bad, you can watch it with friends. Some of the characters are laughable, especially the English dub. Also, there's plenty of gore.
