A good review solidifies your offer, brings authenticity to your brand, and increases trust in your product. Thats exactly what a business needs to increase conversions and trust in branding.
Here’s what a good review profile usually looks like:
A balance of positive and negative comments;
Descriptions of product usage and satisfaction;
Comparisons of a product to competing brands.
Also, Don’t expect users to put too much effort to uncover the truth in the conflicting reviews. Most users will look to the good and bad extremes and make a decision based off the handful of reviews they've decided to read. Thats why it's important to display you're overall rating, as well as the best reviews you have.
