That was the mid season finale of TVD and I don't know about you, but it was less than engaging. Why oh why should I continue to care about Elena's relationship angst? Damon saving Elena from his horrible past? Really? What Damon may have done is cold but they tortured him for five years.
Then we have Katherine happily on the redemption train. Oh dear, she's suffering and dying. Again, why should I care. Katherine at least had some teeth and now she's boring and useless.
I also take issue with their use of the travellers. They are a highly marginalized group of people and TVD has just borrowed their identity to play with. You can't just do that to people. You cannot just take bits of their culture, through in some woo and right a plot. The more I watch the more disgusted I am by the TVD.
Another thing, they know exactly what Wes is and yet they left him on the ground. He wasn't even really hurt. I get that they want Wes to continue to cause trouble for the rest of the season but just leaving him on the floor was weak.
