So here's my whole take on the Under the Dome thing regarding limited episodes or no set end to the series. It's an ADAPTATION. No matter how much they change it or plan to extend it...I can go online and read the entire synopsis of the show! It has a crazy amount of LOST-like intrigue but they're not going to be able to milk to cliffhanger aspect all that much because the basic plot is already known. At some point, I'm just going to want to see the dang wrap-up already and quit being strung along. I don't think they should try and milk it more than two seasons. This is TV serial material, not an open-ended series. I think there's enough interesting tidbits in the book that could lend itself to a "sequel" that could last a few seasons longer, but the events of the actual book shouldn't be strung out any longer than two years. I'll tell you right now, I'll quit watching if it comes to that. It's like it someone was making a TV series of Pride and Prejudice but not actually planning to get around to the whole Lizzie/Darcy resolution for a few years.
