Advertisements The serialized shows - like Heroes and Lost, but even going back to Buffy and Angel - that have season-long plot arcs always work great in marathon viewing. You don't lose some of the details that you do when there are week-long - and longer - gaps in the viewings. The only current show that I can't stand to watch in a marathon is House. I love the show, but since every episode is almost exactly the same from a structure and plot standpoint I can't watch more than 1 or 2 at a time. Really, how many times in a row can you stand watching them guess wrong and almost kill the patient before House finally has an epiphany and figures it out?
