Depends on how you use it. I just keep my application state in redux. Redux itself has absolutely no magic. The only "magic" I see is when you add state diffing and memoization (reselect). And even in this case, it's not really hard to understand what's happening. React with redux is just a big pubsub system, how you set up your application state and how each component interacts with that state will decide how "tangled" and hard to maintain your code is.
