I’ll have to read the paper, but my gut goes against this.

1. For many people, the review is a narrative about what happened. How does one tell a story without using first person? How does one describe a four-person meal without referencing the other members of the party?
2. Most people overuse adverbs. Strunk & White didn’t say “omit needless words” for filler.
3. Verb use: how does one tell a story about bad service without describing the actions of the parties involved?
4. I’m neutral on punctuation, but I wouldn’t be surprised if a glowing 5-star review or angry 1-star review contained exclamation points. These are excited customers, and exclamation points are often used to emphasize this excitement.
