Where are the laughs? Okay, there were a few, but something is just a bit off with The Big Bang Theory this season, as "The Decoupling Fluctuation" followed the mundane path of the premiere.

None of the stories worked for me: not the relationship woes, not Howard in space and especially not Stuart joining the group. While there were a few funny lines scattered throughout the 30 minutes, overall, it was lacking in the laughs department.

Why can't Penny and Leonard be happy for once? As soon as they get together, the writers  pull them apart. It's one thing for them to have issues in their relationship, but having Penny doubt their entire future is annoying.

I want to see them together in a real, committed, loving relationship for once. That can be funny! Amy and Sheldon's relationship is given more respect and that's saying a lot. The writers seem to running out of ideas, because they keep going back to old stories. Sheldon having to keep a secret again? Boring.

I was excited by the idea that we would get to see Howard in space. The potential fodder of space is being ignored for more of the same. Howard's relationship issues with Bernadette and his mother aren't new. The best they have is the other astronauts bullying him - why stay in space for that? He's been picked on plenty on Earth.

I'd love to see humor driven by the space station, the lack of gravity or interacting with the other astronauts in a confined space. The unique environment is being underutilized.Though Howards F-Loops face was worth a few chuckles. As was Sheldon's insistence at making walkie-talkie sounds during their video chat.

Stuart looks to be sticking around, since actor Kevin Sussman has been upgraded to a series regular on the show. It's nice for Raj to have someone to hang out with, but I hope he becomes more integrated into the group. He stuck out like a third wheel throughout the episode.

While that was probably supposed to be funny, I just felt bad for him. The Wolowitz-replacement jokes fell flat and the coffee and creamer one wasn't much better. As his character gets more rounded out, he should bring more laughs.

With all my complaining, there were some funny and touching moments. I've mentioned some above and a few more were the transformers conversation between Leonard and Sheldon, Leonard's puppy dog eyes, and Sheldon's visit to Penny's bedroom.

Sheldon's comment that he didn't want to see his friend hurt was one of the most sensitive things he has ever said. A little salty water may have accumulated in my eyes at that moment. He does have a heart.

Was I too tough on the episode? Or do you agree that The Big Bang Theory is missing its comedic mojo? I have my fingers crossed that the Penny and Leonard situation will correct itself with comedic gold!
