I know out of the box disqus does not have any rating features. Is there anything currently out there that would allow to integrate some sort of star rating plugin with disqus?
A Google search showed a number of interesting options.
You should check out the JQuery star rating plugin.

Another option is jtinder
https://github.com/do-web/jTinder
jTinder is a javascript library that makes rating people, products, images very easy and fast. It is optimized for mobile touch device but has also a desktop fallback.
There's also the rateit
plugin
If you are using react-js
you can use the react-star-rating-input
plugin

React.js component for entering 0-5 (or more) stars
Then there's raty
