In the WordPress settings, you can moderate any comments, such that they are not seen by the public unless you approve them. Also the Akismet anti-comment spam plugin is a must.
If you do allow negative comments, it will actually INCREASE your authority (in my opinion) because it won't seem as if you are deleting the negative ones. In other words, you're being totally honest. I'd even state that in your text requesting comments ("We don't delete negative comments.") People are smart enough to accept a few negative comments as normal. They may even expect them.
Years ago, I was the professional online marketer for one excellent new product ecommerce site, where we told the public that our comments page was unmoderated - and it was. I talked the owners into doing this with some difficulty. But it worked great. We had about 85%, or more, positive or ultra-positive comments and 15%, or fewer, negative.
The product grew from being in one brick and mortar store to being in tens of thousands of stores in at least 3 countries today. And the site traffic went from almost nothing (when I inherited the newly completed site) to 43,000 a month when the project got too big for my one-man operation and the owners moved it to a large SEO firm. The company grew from one woman part time to her and her husband full time to them plus a staff of 6 when my involvement ended.
I think honesty sells.
Hope this helps....
