What happen to Pretty Little Liars ?

Pretty little liars was a good show until they extended the story line
off who is A. My sister still loves it but nobody else and my family
watch it any more i mean the show was good but they need to tell us
who A is and start a different story line with people dying and do
like a big twist or im pretty shure the show is going to go off air
soon.

AND NOBODY WANTS THAT TO HAPPEN>> it was a great show idk jus not that
interesting you can kinda guess what emily, spencer, aria, and
hannah...
