Homeland
GOT
Homeland was supposed to be one season long and end. If that was the case, it would have been really good. But SHO extended it due to its popularity, and it just became stupid after all the events in season one. Shotime does this often, just like with Dexter. HBO knows when to end.
To each his own though, it's all subjective.
Except for the guy who wrote True Blood. Started out great, thinking it would focus on the social impacts of vampire integrating into society. Then it went to vampires in full leather with rocket launchers.
