'The Walking Dead' winter finale ends with a bang

"The Walking Dead" ended the first half of its second season with a bang Sunday night, and the show got a much-needed boost of energy right along with it.

(Time for the obligatory spoiler alert — stop reading, right now, if you haven’t seen the winter finale.)

Much of this first batch of episodes focused on the search for little Sophia, who disappeared after a zombie attack back at the beginning of the season. Nearly every episode after that either followed the other survivors while they looked for her or included a scene or two with everyone talking about how they needed to get out there and look for her.

It made for some much quieter episodes (compared to the first season, when zombies were waiting around every corner), and I’m not sure it really worked for the show.

There were some Sunday nights when I just didn’t really care to tune in. But I hung in there, and the final moments of this week’s episode made it all worth it.

The hour began with Glenn finally telling his fellow travelers that Hershel, the nice old veterinarian who had been letting them all stay on his property, had a bunch of walkers stashed away in his barn.

Hershel, you see, doesn’t see the zombies as zombies. He thinks they’re just sick people who need to be cured (tell that to them when they’re trying to bite off your arm, old man!).

We all knew it wouldn’t be long before something happened to that barn, especially with the angry, increasingly villainous Shane around (will somebody — zombie or not — kill this guy already?)

Rick talked to Hershel and tried to convince him that keeping a barn full of flesh-eating zombies probably isn’t the best idea, but he wouldn’t listen to it.

Then Rick asked (or kinda demanded, really) that Hershel let them stay on his farm and dropped the bomb about Lori’s pregnancy.

Hershel was pretty adamant that Rick and company leave, but started to change his mind after his daughter, Maggie, pleaded with him to change his mind.

To see if Rick could eventually adopt his way of thinking, Hershel took him out into the woods to help capture a couple random walkers they’d trapped in a nearby creek. (I can maybe buy keeping your zombiefied family members around, but randoms in a creek? Come on now.)

With Rick and Hershel away, Shane made his move. He tried to rally the troops (most seemed to think he was crazy, except for the equally unhinged Andrea), handing out guns and telling them they all needed to do something about the walkers in the barn.

Then, right in the middle of his diatribe, Rick and Hershel showed back up, trying to herd the creek zombies into it. Shane went ballistic — think yelling, screaming, frothing at the mouth — and did the unthinkable: He opened up the barn.

The zombies started trickling out and Shane, who was eventually joined by Andrea, Darryl, T-Dog and even Glenn, started shooting them, one by one, as Hershel and Maggie sobbed nearby.

Once the massacre was over, everyone stood around in shock.

Then we heard more sounds coming from the barn. There was one zombie left in there.

And guess who it was? Dear, sweet Sophia (I’m kinda mad at myself for not seeing that one coming!).

Shane and his trigger-happy pals were suddenly frozen, staring in shock as zombie Sophia (Zophia?) got closer and closer.

So Rick — poor, poor Rick, who always has to do the dirty work for this group — took action and stopped her with a shot to the head.

Now that’s what I call an ending. The new episodes, which pick back up in February, better capitalize on it. Nobody likes a quiet zombie story.
