wasted time on PLL. Season 1 and 2 took off good but after that you will be just killing your time to know who A is. and then it will went on and on upto season 7.After certain point just like me if you can't bear it more just GOOGLE who A is and what happened other characters .
Show could be a good time-pass for teens but after certain age point you will find many things unrelated.
Those who enjoyed show Good for them. Have fun.
