Samurai Sentai Shinkenger (2009-10)

49 episodes, approx. 25 minutes each.

Their crossover with (Onore) Decade comprises Episodes 24 and 25 of his series. The order of viewing is: Act 20 --> Decade 24 --> Act 21 --> Decade 25

I recommend viewing The Decisive War (their dedicated movie) after Act 22. It has since occurred to me that a war suddenly breaking out does make sense given Decade's recent appearance.

Their DVD Special still doesn't really make sense after Act 24, but you're free to watch it then, assuming you've also seen The Decisive War.

Their crossover with the previous year's team (Go-Onger) takes place at some point after Act 35. Immediately afterward is just fine.

Come Back! Shinkenger, based on who isn't in it, and what we know from the next crossover, takes place sometime in between Act 35 and Act 44. Its title and coda of course imply that it should be viewed post-series. That's a perfect time to experience it.

Goseiger VS Shinkenger as best as I can fit it into the timeline, via conventional reasoning, occurs post-series and after Epic 30.
