I just started up on this series. Some of the episodes on the first two discs are pretty terrible. But a few of the more "realistic" episodes really standout to me and I quite enjoy them - P.O.V. and It's Never Too Late spring to my mind immediately.
But, my good, it took them a while to finally get the correct vibe for the Joker. His first three episodes aren't very good. Having said that, even in the terrible ones I can still point some sequences or tiny moments that really sparkle.
Great series. It's been far too long since I went through the whole run again. God, do I love this show.
