Constantine

Too bad this got canceled.

Matt Ryan made a great Constantine. All the characters are running from their past mistakes which makes for some repetitive arcs, but the plot was fast-paced enough that it kept it interesting. While Ryan does return in Legends of Tomorrow, the one and only season leaves a lot of plot threads unresolved.

Didn't make it through 2, fuck-awful Buffy-clone

I know that Arrow is doing a crossover with it later this year with Matt Ryan returning, retroactively making it part of the CW DC universe. That kind of makes me want to go back and watch it. I wasn't too impressed by the two episodes I watched, though they had some moodiness to them.
