Dexter is a major achievement in TV history. Michael C. Hall rules as the lead character. I don't think after watching Dexter, I will want to see Michael C. Hall in any other character. He absorbs himself in the character so very efficiently. After finishing the final episode of Season 7, I simply stand in awe as to what more this show has to offer. The plot layout for all the seasons are unparalleled and innovative apart from Season 6 which has some discrepancies. Hence, a small token of credit should also be given to the screenwriters. The important message that this show conveys is although Dexter commits the murders with absolute prudence and canniness, even he cannot control the outcome of his actions. He has to constantly look over his shoulders and cover his tracks as the aftermath of his acts have serious implications. Even his sister is drawn into his battle in order to save him. Jennifer Carpenter is a gem of an actor as well. She exercises her emotions so powerfully that she compels the audience to appreciate her. A very good cast overall and each of their performances stand out.
Do NOT miss this show as you'll never love a serial killer more than Dexter. He'll be your favorite.
