You can have great PR with bad SERPS if your anchor text is for low searched words, but 99% of the time you can't have great SERPS without good/great PR because the two are related. Only time where you can have amazing SERPS and low PR is when you find a great keyword that is searched a lot, you won it, and with very little backlinks. It's a good metric though, compared to just guessing.
