Yeah, those were my feelings. The end was such a let down. It should have been 2 hours, like Lost was. As for Nathan's mom and Linderman and all, Ive heard rumor that the next season will be like a "prequel", and will focus on Linderman, Nathan's mom, Hiro's dad, and all of that generation of people with special powers. In one episode, Linderman explained to Nathan that there used to be a group of heroes, but some fell to evil. I think the season will focus on that story.
