It would appear that I may be in the minority here.
I did not find this episode all that interesting.
Before I watched it, I asked my self what could they do? Part of them were being held hostage, other parts of the group were making there way toward the hostage area.
So, the hostages could escape or not, one or more of the main characters could be killed or not and the group could get back together or not and that is exactly what happened along with the gruesome factor (not to spoil it for anyone that has not seen it yet).
From the teasers, and of course one has to take them for what they are worth, it would seem that they may be going for even more gruesomeness this season.
Maybe the writers will have some interesting story arcs and additional character development. Time will tell.
