IGN: Anyone who doesn't believe comedy and tragedy can exist side by side in a series and do so in harmony should watch tonight's episode of iZombie. And yes, there are people who still need to be convinced darkness and lightness can exist in the same show. "Dead Rat, Live Rat, Brown Rat, White Right" brought the most laugh out loud moments of the season -- Ravi's "It's not alive!" killed me -- but also scenes right out of a horror film and one of the heaviest interactions we've seen. The balance this show consistently achieves is impressive.
