I’m late to The Walking Dead. It’s not that I don’t like zombies — I do, ever since I watched Night of the Living Dead as a five year old. But there are so many shows out there, as well as an endless supply of zombie-themed shows and books. When it came to The Walking Dead, I just couldn’t be bothered.

But I decided to binge watch the show last Thanksgiving, and just before Christmas I caught up. (Part of that time was spent in bed with a fever — zombie shows make for surreal fever dreams). My verdict? The Walking Dead does several things great:

–This show manages to put a fresh spin on the beaten-to-death zombie trope. How? By focusing on the nuts and bolts of survival in a slow-moving apocalypse. Zombies are only one danger. Other humans are nearly as bad (hell, they’re sometimes worse).

–Rick Grimes (as played by Andrew Lincoln) is a hero who is both resolute and plagued by doubt. He is human and relatable. This is a tricky mix that the writers, and Lincoln, pull off.

–With its ensemble, revolving cast, its characterizations can be uneven. Some have remained cardboard over several seasons (I’m looking at you, Glenn and Maggie). but then we get amazing characters like Michonne. She will be remembered as one of the iconic horror characters decades from now. And then there’s Daryl, who has been consistently bad-ass, and consistently compelling. Finally, there’s Carol, who has morphed from a mousy abused woman to a woman with a backbone of steel. Carol has seen the worst of life and she has learned what it takes to survive in this horrific world.

But… The Walking Dead, like Lost, is one of those maddening TV shows that is blessed with brilliance and plagued by arrogance. This show is great, and the writers know it, which trips them up.

Take the episode “The Grove” from season 4. Carol and Tyreese are holed up in an idyllic country cottage with two young sisters. As often happens on this show, things go south. Way south. This episode was sharp and smart and beautiful. It was gut-wrenching and caught me off-guard. It was not a fast-paced episode — The Walking Dead often walks very slowly. But it was one of the most jarring hours of television I’ve seen.

And then The Walking Dead serves up an episode like “Them,” the latest in current season 5. In “Them,” the gang is reeling from the deaths of two beloved members. They’re wandering, starving, thirsty, and trailed by ambling zombies. And they have angst. And doubt. Basically nothing much of note happens for most of this episode, except for our heroes acting out in small, supposedly symbolic ways. Plus, we get a perverse motivational speech from Rick that is about three seasons too late in coming.The writers were aiming for deep symbolism and small epiphanies. They missed. Instead we got an hour of pouting and navel gazing.

Still, the worst episode of The Walking Dead is better than 99% of other TV shows. Here’s hoping the writers don’t repeat mistakes like this. Please — give us more ecstasy and spare us the agony.
