Query: Dexter Delivers

This is a great series, made all the better by Michael C. Hall as the eponymous anti-hero. Without him, the series might have floundered; a lesser actor may not have walked the delicate tightrope between murderous and magnanimous with the same masterful balance. The series is well written, with a very cleverly conceived title sequence, but it truly is the reliable performances which make this show. Highly recommended (especially for those who love themselves a bit of Michael C. Hall).
