I'm a lifelong DC comics fan since I was a teenager and discovered comic books when I was about 12 and started, rather fortuitously, just after the original Crisis. Never looked back and have read pretty much every DC comic since then (have them all on my PC as well so I can look back and re-read all the time 🙂 )
So, yeah, I watch pretty much everything that comes out, TV, movie, animation, the lot. :D
I love all the CW shows and think it's the closest we've ever got to actual comic books on screen, with their serialised storylines and big, crazy characters. I agree, it's not always perfect, Arrow and Flash have both had duff episodes and have struggled at times, but I persevered and there have been some excellent stuff come out of them, especially the crossovers and the Crisis was just all kinds of awesome for me :)
I also watch all the others, unless it gets cancelled very quickly, like Swamp Thing (I don't have enough hours in the day to be able to watch all the TV and movies I want to so I can't afford to waste it on shows that are gone that fast 😞 ) and yes, Harley Quinn is brilliant atm :)
Looking forward to Stargirl, should be fun!
