I think Brooklyn nine nine is a great option! I started watching a few episodes tonight because of your suggestion and i really like it. So i agree i really like the Shady hollow people but i am considering giving up the show cuz... yeah. But i like your idea! I'd love for us to stick together! (Also i think maybe elementary or How to get away with murder?)
Aww I got you to watch B99? Awesome, that makes me very happy, I love that show so much. I was actually a little obsessed with it last season, before SH took over my brain, so it would be a good candidate for me. Only downside is there's not much to be shady about (odd downside to have, I know).
I'm not watching HTGAWM, I'm planning on binge watching it at a later time but it's not really my kinda show by the looks of it (bit soapy/Scandal-y?). I do like Elementary but I don't have a ship there and I think people are divided on Joan/Sherlock so there'd be some rifts. (It's a notp for me actually, there's just something gross about them taking a male character and turning her female and now hey look, they can date! That bothers me on at least 3 levels, possibly more.)
The Flash could be a candidate too (I assume you watch from your icon), I'm not really getting obsess-y feelings about it but I do really like it. And there's already a nice racist section of the fandom for us to be shady about so that's nice. :s
I still hope it won't come to this, but we do have some option if it does, and I love that we all want to stick together. <3 The fandom that shades together...
