Suggested Themes that integrate well?

I’m using this for a list of local resources for the homeless community in Dallas county.
So far it works fairly well. But I want a theme that integrates well with this.
I want people to be able to comment and rate each site. I want it to display “Stars” for each site based on those ratings.
The maps are good, but is there a theme that integrated better with this?
