'Samurai Forever' is a good way to end the series. We haven't seen the last of the Samurai Rangers. They'll be back in the team up with the Megaforce Rangers in season 1 of Megaforce, and the Megaforce Rangers will morph into doubles of the Samurai Rangers in season 2.
I also like the part where Skull picked up Spike. That laugh from Bulk was very funny.
