For me, comparing Dekaranger and Boukenger, I'd say Dekaranger was funner to watch than Boukenger. Dekaranger had episodes worth rewatching, because like what ForeverRed said, "it's like a weekly police drama series." As for Boukenger, the first 20 eps were exciting, but after Eiji made his entry as BoukenSilver, the series went downhill with fewer interesting eps.
Gekiranger may have the annoying Jan like Dekaranger had Ban, but I think it's slightly better than what I've seen in Boukenger. Of course, I still don't like Gekiranger that much and I don't take the entire series seriously (except the final story arc which is totally AWESOME!).
I'd say check out Go-onger when it premieres, I see a whole lot of new potential in that series. (NOT including their horrific mecha) :thumbs: :laugh:
