It's very interesting to compare to Toku, where Super Sentai hardly coasts by on Goranger and actually tends to make a lot more bank off of and a lot more spin-off post-series material for Gokaiger, Dekaranger, Shinkenger etc. -- and then you've got Kamen Rider where post-series Showa stuff is practically non-existent in lieu of Heisei, and even then the first Heisei Rider takes a back seat to the likes of OOO, Den-O, Faiz, W... about the only current Toku that really relies on its roots is Ultraman and honestly I'd still say there's a lot more focus on Zero and recently Orb and Geed there.

It's just such a fascinating comparison looking between Toku and the likes of Transformers, Power Rangers etc which exclusively looks back at its first couple years every chance they get.
