Magento – How to enable star rating in Magento2

Go to catalog -> reviews and ratings - > Customer Reviews->pending reviews and make status to approved.Now you can see all reviews on product page.

I did same thing but the different way. Instead of putting required-entry class to radio, I add new validation rule to that form.

Please put below code in your review form page, it might be work for you:

<script type="text/javascript">
    //<![CDATA[
    var dataForm = new VarienForm("review-form", true);

    Validation.addAllThese(
            [
                ['validate-rating', '<?php echo $this->__('Please select one of each of the ratings above') ?>', function (v) {
                            return false;

                }]
            ]
            );
    //]]>
</script>

Here is the output of validation:

Let me know if you have query for the same.
