Great idea +1 I have a few favourite series that I always seem to select the same episode every time and it is always a nice surprise when selecting the lesser viewed episodes.
To answer the other poster. I would argue that thousands of shows (probably a majority of releases) would work well in random mode. Think of all the series such as Big Bang theory, Will & Grace, CSI, Criminal Minds, House, Modern Family, Simpson’s, Family Guys, Seinfeld … the list goes on forever. There is no need to watch them in order. Only shows that have a progressive plot line would make sense following the air order maybe the Game Of Thrones, Walking Dead, House Of Cards etc.
