Mid season break? Really confusing. I also watched Heroes tonight and at the end of the (new) episode they said they would be back with a new episode in 2 weeks. Do you remember when LOST started having those really long breaks during what should have been the season. It was even worse than this because LOST has these long story arcs and the viewers were left high and dry for an ridiculously long time. Many people just never bothered to tune in again. In any case I sat and watched the show because even a Big Bang Theory rerun is better than the competition.

It is because they did not want to go up against the World Series. The sitcoms take a ratings hit when they go up against baseball. They will be back with a string of all new episodes starting next Monday, November 3.
