Oh? Are we discussing my childhood?
I freakin LOVED the power rangers as a kid. The REAL ones. I'm talking Mighty Morphin power rangers here, before they became a rescue unit, then went to space, then went turbo, then got involved in aliens, then lived on a space colony, then...then......where are they are now? (PS, I realize my order is wrong). Not knocking against Galaxy and Space, though. Those were good too, but the first concept was better (Right around when they brought in the green ranger. That whole arc with Tommy was pretty cool)
Honestly, what I liked most about the old series was that they were normal people. They were trying to finish school, and deal with their own personal issues while ALSO having to bear the burden of saving the world every freakin week. I really liked that. It made them feel more real than when power rangering became a full time job. Plus, it was just plain fun, and funny. And the villains were great (the banter between Rita Repulsa and Zed made me crack up all the time).
Seriously, turn back the series to the old story style (bunch of normal young adults dealing with their lives while also having to save the world on top of that), and have better fight scenes (I admit right up front how terrible the fight scenes were in the old one), and I would most likely give it a look.
....In fact, I can honestly say that the second SNES power rangers game ("power rangers the movie" Despite having NOTHING but the last boss in common with the movie) was one of the games I loved to play most at my best buddy's house. And I still go back to it whenever I want a good retro beat-em-up.
And to answer your original questions:
favorite series? Mighty Morphin (Starting right around the time they brought in Tommy/green/white.)
Favorite song: The original theme. I have it on my Ipod, both the original extended version, AND the powerglove remix. And I freakin love it.
favorite character: ...Probably tommy/green/white. He just had an interesting arc. ...Although blue/Billy was probably a VEEEERY close second. He was in EVERY series for such a long time. Plus, he was a nerd who was actually pretty freakin badass.
Fav Villain: ...Rita and Zed working together. Their back and forth banter was hilarious.
Fav weapon: ...The battleax that is also a gun.
