Although this is not an entertainment blog, I must mention my other favorite show real quickly while I'm on the subject.
Heroes starts its new season in two (I think) weeks. Last season ended abruptly, and left an open-ended question as to Nathan Petrelli's loyalties. Arthur Petrelli was dead (maybe), Hiro had lost his power, Ando had a new power, and Peter Petrelli had gained his power back.
The reason I mention these and no other characters, is because Arthur Petrelli, Peter Petrelli, and Hiro are the only three time travelers in the show (ignore fast girl, the physics of that make me angry, and I doubt the show uses it again).
I have often preached "special powers are always just a plot device", and fast girl suddenly being able to run backwards and forwards in time "because she's faster than light" makes sense in the backwards direction, but any attempts to run forwards in time by going faster than light will in fact - send you further back in time!
Nevertheless, the point I am trying to make here is that hopefully the writers of the show have realized that time travel is an awful power and it renders the plot almost meaningless (if you don't like something, just go back in time and rewrite the show's plot), and it renders the show's direction impossible to follow midstream. I pity any TV viewer who tried to pick up midseason on Heroes, the show was so convoluted that it would have been nearly impossible. If you had started the show midseason, Suresh's character would have made your head wander: why is this character's power getting worse? And what happened to Suresh's search for his sister, Shanti? The writers, bless them, tend to forget details about characters that are primary motivators for their actions and then remotivate them in new ways to follow the new story arc.
Anyway, I am hoping that the writers have said "time travel is neat, but impractical. A better solution is to let Ando and Hiro explore the role reversal, have Peter only be able to acquire powers he comes in contact with after the injection of the serum, and just work harder at writing so the sudden, end of season deus ex machina are no longer necessary.
Other than that, it's my favorite show, by a long shot. And that concludes my entertainment blogging. BACK TO SCIENCE!!
