Once upon a time there were so few things on the teevee for nerds. Now there are actually a lot! So many you get to pick and choose. So many that many of them are bad even if you are a nerd desperate for such things, because you don't need to be desperate anymore!
Anyway, if you want a fun scifi show that isn't pretentious but also doesn't think you're stupid, go for Killjoys. It's a fun genre show that isn't trying to be (pretending to be) SMART but isn't dumb, either.
Season 2 is better than season 1. I have not yet seen season 3 yet.
