I think I wouldn't be excited about this ep if we hadn't just had reruns, but we have, so OHMYCOWNEWEP! and I just hope that the Shamy doesn't become an actual couple after all this. That won't make me happy.

Missed the show too much, cannot wait for epi

Finally a new ep. Feels like forever.

Given that this is only a 30 min. show I don't see the point in watching the promos, it just makes it that much more exciting to watch since I don't know what's gonna be said.

There's a Christmas concert tonight but geek-dom trumps band music

I actually enjoyed the reruns because of the Lp rewatchers club : lmao: the epi we watched was better than anything in this season which has been a lackluster season at best so far. For me

This season has been the weakest so far for me-but I still like it a lot. But I'm more excited this week that usual because we've had reruns-even though I do love Re-Watcher's!

Oddly enough I haven't missed it that much because the last episode was a miss. And there was enough other stuff to watch (catch up on).

Going in with no expectations for this one so hopefully I won't be disappointed.

Didn't love it, but liked it a lot!

the episode was good...pretty funny..still can't stand amy and bernadette

I thought it was hilarious! Especially the 'whooo' 'zack' conversation with Sheldon and Amy. And the 'fight' with Raj and Howard.

Did not like it at all. Season 4 has been off and on weak but The Alien Parasite set new standards for weak.
In the opening Sheldon was so not Sheldon. I don't really think Amy adds anything to the show. The superhero bit was just stretched too far trying to get laughs.

I didn't laugh at anything.

I had to quickly watch The Precious Fragmentation and The Creepy Candy Coating Corollary just to cleanse my palette.

And now I'll go watch Chuck!

Those are good episodes to go to!

The episode wasn't bad, but Penny in only 2 scenes, c'mon writers.

WeBuiltThePyramids

They're picking the wrong girl to give storylines to.

carl1970

Exactly. I could care less about Amy have sexual feelings for Zack. It's like the writers weren't sure what to do with Leonard or Penny when they wrote this episode.
