Well it's not simply a prequel if they re-write future history so to speak. Camerons interference has already altered the fute events we saw unfold in T3. Things might change a lot further during the course of the series.

All in all I'd think a version set in the future where they fight off skynet every week would get kind of stale, I always thought the point of the story was Skynet trying to prevent John Connor from leading the resistance fighters.

I feel like the show is improving all the time even though it still does feel uneven. Hopefully the show will find its feet soon.

Last weeks episode with Cameron / Alison was probably the best one yet...But the one before that where Charlie's wife died was probably the worst one yet.
