big bang theory is now 9 episodes behind in season 9 in Australia stuck on episode 6 and playstation video is up to date , i contacted google play last week and got stuck into them and said they will do their best to have the episodes up soon but have not even had a reply,please everbody waiting keep calling them up as it is a free call anyway and voice your disgust in their service which is bordering on criminal always saying the studios have to pass on the episodes,if thats the case how come we get some episodes the next day then others don't arrive at all. Now this is just a list of shows at the moment that i looked up and are 4 to 5 episodes behind. ARROW , THE FLASH , SUPERGIRL , GOTHAM that they did not give you the final episode 22 which i mentioned on the phone and sounded surprised you have got to be kidding please everyone bombard them constantly by phone as i don't think they take much notice of these reviews.

I avoided this show for so long because i couldn't get into it. It wasn't until i was on maternity leave & needed a new show to watch was when i found out this show is actually pretty good. While some characters are super annoying like Penny, Bernadette & Howard, the rest are funny and make it quite an enjoyable show. Just like most people Sheldon is my favourite character.

You can tell this once bright spark of a comedy is just hanging around for the money, especially since you only get 17-19 minutes of one-liner scenes per half-hour. Where once the characters were intriguing for their extreme naivety, now, they are stale and one-dimensional.
