Currently, everything I watch, with the exception of Dexter is just on a mid-season break. But I concur, the Dexter finale did have a twinge of shock value. I wasn't really surprised by any means, but the writers of the show are very good at what they do, and the final scene was just masterfully done.
Also eagerly looking forward to the finale of the now canceled Dollhouse (d*mn you FOX). This season of Dollhouse has been some of the best TV in a long time, it is just sad that TV stations can't seem to take into account that there are other mediums of watching TV now (IE itunes, amazon, hulu, DVR). They need to stop deciding on the fate of shows simply by the numbers of the first air. That is complete BS...but anywho..
