I have watched this one, i got interested in watching it after i saw "Gransazers" i saw Gransazers for like 5 years ago and Power rangers 4 years ago.. since i have watched both so i can tell you what was best to me.. I think Gransazers was way better than Power rangers so if you haven't watched Gransazers yet i would recommend you to watch it, Power Rangers lacks in story line and seriousness it's like you are watching a funny show unlike Gransazers
I don't really watch it anymore but I probably would if I were surfing through channels on TV and saw it was on. I liked Power Rangers a lot when I was younger. I nearly dressed up as the pink ranger for Halloween when I was about 9 but the costume didn't fit.
In Lost (Exodus) Walt is watching an older version of Power Rangers SPD I think.
