Am kind of enjoying Killjoys so far. Best way to describe my first take (from the first two episodes): Take the firefly setting (minus the cowboy thing) and make the main characters bounty hunters tracking down people the Company wants dealt with.
Add in a talking, intelligent ship a mysterious assassin upbringing for one of the chars and somewhat over the top sci-fi action and it's a good time. Don't expect deep plots and you shouldn't be disappointed.
