If Google will fix the user interface of the box, than it will be acceptable.

(1) let the user correct a rating if tapped by accident

(2) offer the option to leave a comment

Sadly, many users just don't read past the title. And users familiar with other suggestion engines (pandora, etc) expect to teach the system their taste and relevance.

I'm a developer, and I have the same rating fall in my apps too. Re-scaling is good, as long as it is fair. I have no problem with making it easier for unhappy users to vote, but I do have problem with a suggestion box which misleads at least some users to rate by mistake. And I also have problem with Google surfacing apps deleted so long ago that the user has no chance to remember what it was. And once the user taps on any star, the rating is registered - no way for the user to correct a mistake or to explain a negative vote, so the dev could do something about it.

It's just Google being careless about the devs. And it was a surprize for me to realize that. I thought better on Google before it started.
