I never really watched the original run of Veronica Mars outside of a clip here and there, so going in I didn’t really have any warm memories though I know some avid fans didn’t care for this revival but for me, I found it passably entertaining.
Justice League Dark is a middle-of-the-road entry into the DC Animated Universe. It’s also a bit inside baseball in that probably die-hard fans of the comics will get something out if it while others will find it crowded and the magical elements even made it harder to follow.
