I'm not caught up on Flash, so I haven't gotten there, but Arrow was pretty good. This whole not telling about Sara thing is annoying though, because its going to come out eventually.
Though at some point it feels weird when the two shows don't interact as much as they should. I mean, I was watching Buffy and though I've never actually watched Angel, the two shows interacted as much as they needed to and it was realistic.
Though, I mean, if the League of Assassins is gonna straight up murder 50 people, maybe call Wally? I mean, he can literally be there in a Flash. That's his thing! It's also a little weird that there hasn't been any superpowered people on Arrow... besides Wally, ofc.
