But my point is that Super Sentai
got along for half its existence without there being such a thing as Power Rangers
, so there's no reason to believe that its viability in Japan would be affected by what happens to its American adaptation.
Besides, Law & Order
isn't co-produced by a toy company. As long as Japanese kids (and adults?) keep wanting to buy new Sentai toys, Bandai and Toei should be able to afford to keep making the series.
