Dent is pretty much Brock but instead of fixating on women, he fixates on everything. He's likeable and not too imposing. Considering Brock is such a old favorite, he's really done a good job replacing him. Yeah, I'd still prefer to have Brock over him, but I'm happy that Dent is almost as likable. His Pokemon are likable and his interactions with the group are good, i.e, he gets on with Iris as much as he does with Ash. So no terrible three way dynamic like DP had with Brock.
