Loved 'em all. But to me the darkest of the bunch has to be Aba. It's the only one that comes closest to Timeranger. Deka was like sentai crossed with a lighter kid-friendly version of CSI. The darkest things in Hurri were the Gouraiger arcs and Shurikenger's death. As for Magi, the Wolzard saga was like an extended version of the two Dairanger eps that had Ryo's father in them. Haven't seen Bouken, but from what I hear, it's far better better than its American counterpart. I just wish for next year's sentai they get the head writer for Jetman, Dairanger, or Timeranger to return and turn in something like those 3 shows.
