Shining example or horrible warning?

I like movies, it's true.  I might even be a movie buff.  I also happen to like quite a few TV shows, which are similar to movies but have a somewhat different time scale.  The longest movie is maybe four hours, five tops.  But TV shows seem to go on forever.  Take "Friends," for example.  It's like a movie that lasted ten years.  People DIED before they got to see the end.  There's no way to fix the big time suck except for to not get involved in the first place.  It's already too late for me in some respects---I could spend the next five years of my life watching "Psych."  But save yourselves.  Don't start something you may not be around to finish.
