Trailer for season 6 looked pretty solid... I'm definitely excited to see this come back in December.
It'll be interesting to see how they move on from the end of season 5 and the surprise unceremonious death of one of the leads due to the actor getting fired (omitting name for spoiler sake). By all accounts it seems like it was the right decision, but I will miss the character and will be real interesting to see how the writers move on.
