Especially with an automated slider. Sometimes I scroll down to the bottom of my page and only 1 review is listed because it's the last slide and it stays there forever, making it look like there's only 1 review for the business unless the user uses the arrows.
I think it would be much better if the slider was almost like a continuous carousel (like a circle). Ideally I'd love to manually/automatically advance through to the first review after the last review is displayed. Seamless wrapping behavior would be ideal, but even a "jump" back to the front would work.
