There is a valid criticism at the core here, that the JS community jumped a bit too quick on Redux/Flux. Even the author of Redux said quite a few times now that you should not blindly use Redux, but only if you see an actual need for it. I liked Redux when I experimented with it, but it is not a panacea, the advantages you gain are not entirely for free, and it might not be worth the boilerplate and complexity if you don't have a very complex application.
