Game Of Thrones.
I came to hear about this show from a friend of mine who used to talk very much about the show. On the very first day he created such a hype in my mind about the show that the very next day, I downloaded all the seasons of this show and started watching it.
Now there are 5 seasons of the show. 6th season is currently being aired on HBO. Each episode is of nearly one hour.
The plot is pretty interesting. I dont want to give any spoilers because I want you to watch it youself. I would just say that the show is worth all the hype.
