Camden was the first of the "retro" ball parks after the decades of similar cement, brutalist monstrosities that sprung up, and it was a pretty big deal because of that when it opened, and it attracted a lot of people to come check it out.
Personally, I love it. Well designed and constructed, great location in the city, fantastic sightlines, minimal signage/screens, well maintained, etc., etc.. Hugely superior to the hodgepodge mess that Wrigley is, IMO.
