iZombie

Original premise: Liv is a doctor is accidentally turned into a zombie. She becomes a medical examiner in order to have access to brains. After discovering eating the brains of murder victims gives her flashbacks and moments leading up to the victim's death, she helps a detective to solve crimes by pretending to be psychic. A side effect of the brain eating is that she may temporarily acquire skills or idiosyncrasies of the victim. Meanwhile, Blaine, another zombie, is turning rich people into zombies to extort them in return for brains of people he's killing.

How it went: Pretty much everyone in the main cast is a zombie (or were-zombie), there's an evil corporation, an entire city full of zombies, a good guy private military contractor that turns into a bad guy private military contractor, and etc. that I won't spoil any further. And eating a brain pretty much makes you take on that person's entire personality wholesale.

The thing is, it was great! It ended pretty strong without wearing out its welcome or getting too absurd plot-wise. Meanwhile everyone in the cast is clearly having fun with the over-the-top, flanderised personality mechanics, and it's just fun to watch.
