That's what caused me to drop Jessica Jones around episode 4. Just not my thing. I remember having to drop Battlestar Galactica for a time as well because it got so bleak.
Daredevil is still my favorite of the Netflix Marvel shows.
Anyway, I finally found something else the right length to watch while I'm on the elliptical: Superman: The Animated Series. I missed out on a lot of these when they came out, so being able to watch them now is pretty great. Of course, the Batman series before it and Justice League after it were also amazing.
