Honestly the show was good but they told a whole story I don't think it needs a season 2

Broadcast is about daily/weekly consistency. The people still watching don't want new stuff, they want reliable stuff.

streaming is expensive to maintain, so they cut cost everywhere, 8 episode seasons, 1-2 season before cancellations, and extremely long hiatuses, like 1-2 years for 8-10episodes each.

marvel shows before disney got them cancelled were "great" under a different network/studio(like AOS, x-men spinoffs) they had a more robust arcs.

I am convinced they saw that Wonderman was popular and they're going to translate season 2 to a movie for box office revenue instead of Disney+ subscriptions.
