“iZombie” is fun. It’s technically a DC show, though many people don’t consider it one (since it’s based on a Vertigo comic, not DC proper). Season 3 just started this week.
I loved “Frequency,” but judging by its abysmal ratings, not many others did. It hasn’t been officially cancelled yet, but undoubtedly will be.
I’ve read good things about “The 100,” but have never gotten around to checking it out. I need to do that at some point.
Of course, “Whose Line is it Anyway” is always good for a laugh, but I suspect you were only asking about scripted shows.
