Jeff's taste in games is super weird, there's probably more games I like that he dislikes then there are games we both like. Doesn't change my opinion of him that he's a smart, funny dude, and his comments on the industry and games journalism is extremely sound.
Also, I didn't find Gwyn disappointing because it was just a dude, he was just a shit boss in comparison to Old King Allant.
Vergil is just a dude and his fights are badass.
