I've had a love-hate relationship with Dexter since about season 4 (note that only these first seasons are recapped in this trailer for season 8). The regularity in which you can predict when in a season episodes will become pointless or go off arc is amazing, and more then a little disconcerting. The seasons tend to begin and end strong, but no arc since the Trinity killer has lived up to the potential they exhibit (this past season was a traffic accident of potential fantastic plots, none of which really developed into anything). So put me in the column that will be glad to see the show end this summer, long after it outlived it's own usefulness.
Plus Deb may well be the most annoying character currently on TV, and it doesn't look like she'll be getting any less so. But having watched this trailer, which also makes no reference to the return of Yvonne Strahovski, I know 100% that I feel no connection to these characters anymore. I'm not interested in them, or how the show will end. And I'll be watching it only out of deranged obligation, and to make certain it actually ends.
