Not negative as such, just didn't hit the mark that their marketing material was promising.

It's great for pull down refresh lists etc and I even had success doing dynamic insertion when an item in another view was updated (though I had to use a different graphql client to do the inserts ironically) but it was sold as replacing all need for redux for example for state management and that it would sync seamlessly with a graphql backend and unfortunately (maybe it was me) couldn't work out how to do that so ended up using redux as well.

What I was lead to expect is that you subscribe to a store which is dynamically filled and updated by Apollo (which handles synchronising local and remote and loading from scratch etc).
