I admit that I'm pretty new on the Power Rangers bandwaggon compaired to some of the other people in this fandom. I got into the show over the 2010 hiatus, and as such, this was the first truely new episode of Power Rangers I've ever got to see. I wasn't expecting a masterpeice (how can you with this franchise) but I was in fact expecting a pilot episode. Recent evidence has shown this to be the third episode continuity wise... but I didn't know that at the time of the airing. Nobody did. The result is that for a long time after this, and still a little bit now, I hate the character of Mike. Arguably, he's one of the best actors of the bunch, but at the time his character was given so much attention (notice the early episodes, where the female Rangers get hardly any lines while Mike usually is on par with the leading Ranger-of-the-Day) that he became annoying very very quickly. No, it turned out that spot was designated for Jayden.
As an episode by itself, it's average. But as a pilot episode it should have introduced every Ranger and not just one, it should have given Bulk and Spike a proper introduction with the Rangers, and it should have taken the time to introduce us to the villians. Seriously, if it wern't for the exposition on the back of a Megazord Toy I bought, I would have no idea who these villains are and what they wanted. That's a bad sign when the toy company is paying more attention to the story than you are.
