Hingle was fine but honestly he just seemed like a regular police commissioner than Gordon to me. Watching Batman Returns/Forever/B&R ( I never saw the first Batman until I was already a man, by then it was nothing to me but blinding) as a kid I genuinely had no idea that was the same Gordon in B:tAS.
Oldman was perfect, yeah. Not quite as good as JK Simmons' Jonah when it comes to nailing that supporting character, but great.
