I love me some Power Rangers xD
I haven't kept up with the later series, but I've been meaning to, since a few of the more recent ones have had some pretty nice throwbacks to the classic series from what I've heard. (Tommy being in Dino Thunder, the episodes 'Once a Ranger' and 'Forever Red'. As you can probably tell by all that, my definition of 'more recent' is basically anything after MMPR.
Though I have heard there's a lot of classic throwbacks in the most recent series, I have yet to see it for myself though. So I think some time I might try doing a big marathon xD
