And after some time you think its going to end and your already afraid of the very same end, but then it happens they lengthen the show or the series.
After some time you see that it isn't the same series you watched at the beginning.
The show/series gets boring and it seems like they just want it to go on forever.

Then you start wishing for the end because it doesn't make sense anymore.

This has happened to me a lot of times and I personally hate it when they do this to my favorite show or TV series. They make a soup opra out of it just so that they can have more episodes without caring for the events in the series.
Do you hate when this happens, I mean it's great to watch a show but everything has to have it's end sooner or later and it's better sooner when it's good then later when you start to hate it.
