while T3 had some pretty bad writing, you cant really knock Salvation, its a damn good film. and trying to argue the TV series was better or even equal is laughable. Personal opinions aside, the TV series is little more than fantasy fan fiction, if you are a fan of the Terminator universe (which i am), this isnt worth watching as nothing here translates into the universe.
the series has good action, i will give it that, but the writing and acting are about on par with T3. there is a reason the show was canceled and wasnt even meant to come out (only reason it did was beacuse the writer's strike, the episodes were done and FOX needed some new material when all other networks were barren)
