How can I view only one star ratings in Google Play Store?

I find it quite annoying that there is no easy way to sort the reviews of an Android app: - neither can I search for certain keywords that may appear in a review. - nor can I change the sort order, i.e. I can sort by rating, but if I want to see the 1-star ratings. I have to scroll all the way through thousands of higher ratings. I am feeling quite tricked by Google. Of course it is obvious what they want to do - hide the "bad" ratings from the users. But seriously, it's not very customer friendly :( Are there any web apps or sites that offer detailed sorting options for the Google Play Store?
