OK, almost to the end of season 1 and I'm still watching Heroes. Here's one reason I know I'll be happy with the season closing episode:
A modern TV creator like Kring can't think about just the next episode. He has to think about a world audience and plan several seasons out. "A big complaint for Lost was that you had to wade through too many shows before something happened," Kring says. He is committed to wrapping up story lines each season instead of sinking too deeply into a meandering mythology. "The apocalyptic event in Heroes will be resolved in season one, and we'll move on to something else in season two." (Wired)
Yes! This is exactly what I've been telling people I wish TV shows would start doing. What I like about shorter-run British shows vs. American series, the latter which feel the need to draw major plot lines out over years. (Never mind if you really know how long the American show will last or whether it'll be cancelled before the plot lines are wrapped up.)
I don't need everything wrapped up each season. But don't end a season mid-episode. Take a lesson from book serials, like Harry Potter.
