The fact that it can function well as a standalone series. The biggest example would be episode 4 where it is the start of the non-tribute episode. It simply focused on GokaiBlue, and it worked very well.

There's also the fact that the cast are highly charismatic, iconic, lovable, and written well. While not all of the Gokaiger receives the equal amount of focus, at the very least each and everyone of the entire team has an arc, something that is seldom seen in series after Gokaiger except Go-Busters. Because the biggest criticism of Sentai especially lately is that either they focused on Red too much, or the entire team is underdeveloped.

The characters being written well is why I have hopes for Kiramager and so far they are leaning to that. And charismatic teams are pretty rare too, the last I remember was either the LuPat (still heavily focused on Red, or rather LupinRanger which we all know), and Kyoryuger (no need to say about this one).
