This show is brilliant. The bad reviews and ratings are because, apparently, everyone pirates or doesn't remember what a dvd is. This content has never been free and will never be legally free. Watching it on TV will let you watch an episode or two a day, but the reason you buy a dvd/rights to digital content is to not only watch it whenever you want but to support the show... You are all mentally challenged -_- I'm 'only 17' and I understand this, what did that day about you, you filthy, awful trolls....

This show just isnt funny. It tries so hard to be but I personally don't get the humour. I find it too obvious and the characters are irritating. Also kayley cuacos acting is atrocious. Plus what a rip off don't waste your money. And comparing it to friends is ridiculous friends was in a completely different league to this friends was actually funny, every episode had something funny for thw audience characters were well structured as were storylines and the acting wasnt terrible unlike this.

Watched the entire thing more than once, i will admit that its not as geeky as it was when it first started but then the characters have grown up somewhat. Sheldon is annoying but fun to watch, at least leonard has stopped saying thank you after having sex;(we hope), penny penny penny looks much better with long hair. I just hope it doesnt run for 25 years and turn into the 'friends' of channel 4. Great show!
