The trifecta of a strong Japanese property is TV show, toys, & video games.

Super Sentai and even Kamen Rider have always lacked on that third one. Franchises like Pokemon, Yokai Watch, and Beyblade have been able to push endless amounts of toys and accessories because there's enough in the show and games to keep people interested consistently.

Narratively, I'm not personally into the idea, but a stronger connective tie between each season ensures people don't feel left out in the cold after a season ends and we move on to the next series and the next wave of toys. You can only do that a few series in a row before you burn out and stare at your toy collection that ceases to have meaning and relevance.

Ultraman does a good job at keeping each series connected and feeling relevant. Zero was a popular ultra and he still makes appearances that are more than shallow cameos.

Again on a personal note, I think smaller teams are better. There's just not enough time to build character and have growth and adequate arcs when there are more than like 6 rangers.
