So that leaves out Game of Thrones
Nope. That show is for sociopaths.
Walking dead
Nope. Don't like zombies.
Legends of Tomorrow
The premise of that show is to save a kid who was killed.
Agents of S.H.I.E.L.D.
When did they kill a kid on Agents of SHIELD? Keep in mind I haven't watched this season at all.
Daredevil
Which kid did they kill in Daredevil?
Gotham
Stopped watching Gotham when Fish started scooping out her own eyeballs.
Powers
Are you kidding? That show was terrible. I barely made it through the first episode.
Doctor Who
Nope. I never had an emotional attachment to it from before it was revived so I didn't jump on the bandwagon when it came back.
Torchwood
Nope. Never watched the new Dr. Who, so I didn't really care about Capt. Jack & co.
Come to think of it pretty much every genre show that isn't specifically aimed at children has featured a bad guy killing children and sometimes good guys killing children. And every cop show, And every soap opera, and western, etc.
So what you're basically saying is you only watch comedies, reality tv, and game shows.
There are plenty of genre shows that don't kill kids. There's also a difference between shows where kids die as a matter of other events and where kids are specifically targeted for assassination. The latter doesn't happen all that often and is what I find objectionable.
