Re: Wifey's viewpoint...
"I have never seen so much mental diarrhoea in my feggin' life, the blokes are stereotypical nerds, and the 'eye candy' must be thick."
I used to think that, then my wife started watching it and "made" me watch it with her from the beginning (she caught the "bug" from her 80yo mother who loved it). Penny, the "thick eye candy" is a deeper character than she first appears, eventually ending up as a high powered pharmaceuticals sales rep earning significantly more than her experimental physicist fiancée.
The character evolution/development is very slow, spanning multiple series, which is actually a refreshing change from so many TV series where they are so unsure of getting renewed for a new series that they rush everything into the first series then scramble for new material when they do get the next series commissioned.
Still, all that considered, if you don't like the show then you don't like the show and I'm fine with that.
