This is one of the best tv series I have seen so far .I can assure you that it’s worth your time.every season comes up with something new.more thrill , more drama, more suspense. First 3 season are amazing then the story gets little slow in 4 and 5 season but when you get through season 4 and 5 you will gain more interest in knowing what happens next.season 6-7 will be the best. you will not stop watching it if you get to season 6 , the acting of all the character are amazing and the story keeps getting better and better so I would highly recommend it to watch and it’s totally worth your time.
