Doesn't explain why they didn't start with Hurricanger when they switched to Sentai then (no Disney involvement in the Sentai). Or use it now. I still find it puzzling that they dub Wild Force and then Gaoranger, when half the footage is shared, and many plots are identical. If Japanese culture wasn't the reason for not using Shinkenger, there's no reason why they couldn't have gone with Hurricanger this time, which wouldn't give deja vu feelings to viewers since they never had Ninja Storm.
