Killjoys and Dark Matter were such guilty pleasures of mine. I know it's all the common sci-fi tropes, I know it's cheesy as hell at times, but it was the perfect show to just relax with in the evenings and have some fun.
I also do love Expanse but sometimes you just want something that doesn't take itself that seriously. I miss having sci-fi shows like that.
I agree about Killjoys and Dark Matter. Though it is quite galling that the one that went in with a full 5-season story arc panned out was the one that got cancelled.
