Thanks for all those links. I'm a big fan but this stuff I completeley missed...The unaired pilot was never aired because it sucked, as even Lorre admitted. It just looks too "nerdy" and therefore they had to introduce a new character, Penny, to allow the mainstream audience to identify.And, hey, those characters are not REALLY aware of their problems. Otherwise they would solve them. They all are happy to live the life they have in the end because there are more pros than contras.
