Sure, many were initially attracted by the geeky humor and the original jokes featured in the show, but it also presents a unique love story that no other show on television has managed to offer so far, making it a great show for a large number of people.
It has also done a great job at making nerd culture more mainstream and accepted, and has portrayed computer geeks in a completely different light for a lot of people, something which the show has received lots of praise for. At the same time, some have criticized it for portraying that culture in the wrong light, but this seems to be a vocal minority more than anything else.
In the end, the show is coming back for at least one more season, and it could be the most dramatic one we’ve seen so far if the current indications are true. In a few months, we should have a little more detailed information about what’s coming up in season 9, so stay tuned.
The writers should put Sheldon and Penny together. All this brother/sister thing is a hint of how much onscreen chemistry these actors have ALREADY before they even begin. The other couples, particularly Sheldon and Amy seem really forced. Sheldon is an annoying jerk sure, but he’s way out of Amy’s league. Plus I just don’t believe a girl like Penny would stay with Leonard.
