I know only what has been said here about the reboot - it sounds as doomed as it is abysmal.

Season 4 was a good concept, it was just a shame about Riley - who admittedly was meant to be a bit rubbish, but who just did that too effectively. S6 starts brilliantly, ends intriguingly, but sadly has a longeur in the middle which includes the single worst episode of the series. And 7...I don't know, the pacing is off (Caleb eventually arrives, is invincible for a couple of eps, then dead) but that aside, I think it's judged too harshly.
