Here's just a few examples of listings with mostly fake reviews:

Most top listings are saturated with fake reviews. If you want to understand the depth of the fake listing problem, look at the thousands of people trying to create new listings in high-competition markets. Search Amazon for:

    "silicone oven mitts"
    "bamboo cutting board"
    "meal prep container"

Click any result, then scroll down to the "Sponsored Products" section for that item. Repeat this, really dig down into the "sponsored" lists. Notice the amount of copiers.

Now look at the reviews. For new sponsored products in these categories virtually all of the entries are from review-mill programs. There can be hundreds of fake reviews on a single listing. Many of the negative reviews you may see on these are fake as well, from competitors!

Review-mill programs work by having the reviewers buy the product through amazon (they are reimbursed or discounted). Then they do a write ups. Many are short and organic looking, the more easily spotted ones contain lots of text and multiple photos of the product.
