Well, it’s 2 July here so…. spoilers.
Regarding the ending and set-up for the next season. ISTM that ‘heroes lose their powers’ is a pretty well-worn trope in the super hero genre and, although the family dynamics are an interesting part of the show, I hope they don’t draw out getting their powers back in the next season. I’m hoping for a time jump - something like ‘4 years later’ (that will get us out of 2019 to the present too, and deal with Five’s aging) and we get to see how each of them has hilariously progressed (or not!) as normals before, whoop, their powers mysteriously start to reappear. And of course… APOCALYPSE!
