I was thinking what do you think is the worst thing about a show? Is it the bad ending or a cliffhanger? I have always felt it was the cliffhanger. But a bad ending can come in the second place. For example in the show "How I met your mother" SPOILER ALERT! As the show was coming to an end it was revealed that the writers killed off the mother and it was six years ago in the future, and Ted ends up with Robin. Shouldn't the show be called "How I met Robin"
