LOST

A while back, my very favorite shows was LOST. My family and I were obsessed with it. I was hooked from the very first episode, probably because of how dramatic the show was. Seriously. Constant drama. I loved all of the different personalities on the show and each episode always left you with a cliff hanger. However, as the show progressed I found it getting more and more confusing. Halfway through the series I stopped watching because of how confused and frustrated I would get. It got me thinking, how do some series keep viewers' attention for 10+ seasons? How do certain series manage to maintain their viewers' intrigue?
