Remember: you're more invested in your application than your users. Even if it's possible for them to have a dialog with you to fix their problem, they may not care to.
Posting a negative review is not part of that investment - it's just a cathartic release, and after that, they move on. If you're selling a relatively cheap application that your users don't need (such as a comic-viewing app), you may only have one chance with your users.
