Oh god yes.I missed "Living Witness" first run and didn't see it until several years later after fandom had built it into this "must not miss" episode. I was incredibly disappointed.
Expectations is a double edged sword, if you watch something that gets rave reviews you go in with high expectations so there is a high chance you'll be dissapointed. The opposite is true as well if you go into something after hearing negative reviews you are more likely to be plesently surprised.
In my long experience with entertainment:
Expectation = Disappointment
Bigger the expectation = the higher the chance for greater disappointment.
Where was I just talking about this.....
anyway, my experience is if you go to a movie with expectations... go ahead and take a coffin with you to bury it in. Same with TV. Very rarely, so rarely as to be all but unmentionable, expectations are met in film (movie/tv). Very rarely.
