Ok so I just finished season 6 and I must say the wait could not feel longer for the seventh season
The inconsistencies with Travis' character ruined it for me. Although by the end I was really feeling his bad guy regime. He shined through as a sick minded monster, much better than his performance in the wormwood episode. Would've liked to see a reprise of Gellars character. It feels as if his time was cut short and he never got the conclusion he deserved.
The start of the last episode was perfect. The camera shots, narration and music really outlined Dexters struggle and what he had come to. But the whole season was filled with messy kills and risks, that ultimately backfired on him.
I mean, why kill Travis in the church everyone expects Dexter to be at? I know it's about symbolism for what Travis has done, but it's such a HUGE risk. At any time he could have had an officer or detective drop in and see how he's doing. Which is exactly what happened.
