Is it possible to allow users to give half a star on reviews? eg 3.5 stars?
I'm asking because a lot of reviewers like leaving x.5 stars and are left to just "say so" in their reviews. The totals for the product already add up to x.5 stars sometimes, so it doesn't seem like this would be a stretch to implement.

First of all, if we wanted 11 stops on the scale, we'd go with 0 to 10 instead of 0 to 5 with halves.
Second, we specifically chose a scale with 6 stops and not 11 because we think that works better when you have multiple graders, and can't know what the specifics that a grader uses are. It's pretty clear in a 6-stop range that 0 is terrible, 1 is bad, 2 is not good, 3 is not bad, 4 is pretty good, and 5 is great. But when you introduce a ten-stop system, some people think 5 is average, and some people think 7 is average. More variation means more interpretation, which means less usefulness.

That's not the same thing though - the equivalent of "7 is average" on that scale is 3.5 stars. Nobody is going to think 3.5 is average.
When it looks like it's out of 5 stars (even if it isn't, like you're talking about), 3 stars is clearly mid-way. If you take a quick poll in the office, I bet that's what you'll find.
You're 100% right if it's labelled as 0 to 10, but not if it's kept at 0 to 5 with halves.

I just had another look after leaving a review. Since you use a dropdown to select the rating, you can actually go even further to be clear - it can look like this when you expand the dropdown:
1 star - Not fun at all
1.5 stars
2 stars - Not fun but not terrible
2.5 stars
3 stars - Average
3.5 stars
4 stars - Fun but not fantastic
4.5 stars
5 stars - Among the best
Note that 1 is as low as the current ratings go, not 0.
