Ooh, fun! I'm glad to be a bad influence. ;) I'm going the exact opposite direction: started with Legends of Tomorrow, moved on to Flash and then to Supergirl, which I'm currently getting caught up on. I never have managed to get into Arrow; like you said, it just looks too dark (though maybe once I've run out of everything else, I'll go watch it -- at least the necessary episodes to get backstory on various Legends of Tomorrow characters).
