When I started watching this series I was pretty skeptic because of the hype created around it. I was like whats so great about it. But just the first episode was enough to tie me to it. Until now there are six seasons and the seven season is airing pretty soon.
There is a thick plot with enough sub plots and the characters are well handled. Inspite of the number of sub plots there is not one place you get confused. Its clear and yeah of course super interesting. The cast is the best, be it their acting skills or screen presence or attire, everything gets an A.
Some people find the sudden twists and deaths of favourite characters unacceptable but for me these are pretty necessary for a standard story line. The writer has used his imaginations to the fullest and the directors has proven worthy by bringing it on intelligently to the screen. Each and every sceen is well written and directed.
