I absolutely have no interest in this, but somehow that trailer did remind me how good season 1 (and somewhat less, 2) was. I almost feel like getting back and finish watching the original series. I ended somewhere with the time travel and twists in personalities and such.
It looks all right. I would give it a 3 episode try.
It does remind you of when it was good. But, did you get the feeling you were supposed to be super psyched for HRG, as if he was the hero of the story??
