Chuck is my favorite for a long time. I never seen a show that mixed action, drama, comedy and romance so nicely like Chuck did. The show only survived because the fans loved and believed in it so much. After every season nobody knew if it was getting picked up again. It was a blessing it reached 5 seasons. Although a lot of fans didn't like the ending I thought it was bitter-sweet and left for our imaginations to figure out the unanswered questions. I re-watch every year.
