I'd say that Selina in general was never really done justice in the DCAU, and her relationship with Bruce was fairly weak as a natural consequence. She's ahead of the curve compared to Babs, certainly, and the rights-activist socialite who thieves out of a combination of mild social conscience and strong boredom was a good distillation/revamp and a really strong starting point, but they just never seemed to be inspired to take it anywhere past that the way they were with their Ivy revamp or their Fashion Designer Lana.
