They really need to end this predictable show. The woman playing Penny is a terrible actress with her alcoholism and don't care attitude. The person playing Sheldon is a childish pain in the arse, as is the person playing Leonard.

There is general encouragement from the higher authorities for the average people NOT to illegally download programs like this, yet, when we legitimately purchase season passes on places like Google, they fall behind. This isn't the only program that is not current, and that is annoying.

I love this show but when are the new episodes arriving? Been waiting months and paid just under $50 to watch episodes online but there's only been 6 so far. I want a refund!
