Can't really agree. Gokaiger was my starting point and the Gokai Changes were one reason i got interested in Super Sentai and wanted to watch more. I wanted to know more about those teams and so i started watching.

I think the best way to start is think of a topic of a sentai that may interest you (in my case if not for Gokaiger it would have been dinosaurs) and just start watching the show. If after a few episodes you find it not apealing just switch. That's how i do it anyway XD

I'm with you. I had only watched Shinkenger (and random untranslated episodes of other seasons I could find online in the Limewire era of internet file sharing... oy) before checking out Gokaiger, and I thought it was a blast from start to finish.
