Nip/Tuck,an American television drama series created by Ryan Murphy and broadcast on FX Networks, use a little nipping and tucking of its own after the mediocre fifth season that saw a lengthy hiatus at the hands of the writers strike. Fortunately, it seems that things might be getting back to “normal” for McNamara/Troy.

But the premiere of season six, which will be the show’s last, hints at a team that has grown weary of their own creation. Dull, confusing, and simply uninteresting, “Nip/Tuck” looks like it might go out with a whimper instead of a bang.

The premiere of season six, “Don Hoberman,” raises more questions than anything else. And not questions about where it’s going but about what the hell happened. Firstly, who thought that Katee Sackhoff (“Battlestar Galactica”), who memorably played Sean’s girlfriend Teddy in season five, could be replaced by Rose McGowan and no one would notice or care? The move from the “Bewitched” playbook is a head-scratcher not just because it’s a different actress but because McGowan brings a completely different energy to the character. It doesn’t feel like Teddy of season five.
