I had trouble getting the video on the Nick site to play -- it was okay but posterized at first, but just as the Rangers announced themselves, it became random blobs of color.
And come on, "Sneak Peak?" It continually amazes me how many people forget how the word "peek" is spelled when it's prefaced by "sneak." Though not as much as it amazes me how little interest supposedly professional websites have in proofreading.
As for what little I saw and heard of the preview, it seems there is an effort to emulate elements of MMPR -- the background music when the Rangers first arrived evoked the MMPR theme, and their henshin phrase is the rather boring "Go go Samurai," evoking the MMPR theme's lyrics.
