Indeed. All a review really needs is at minimum to be a couple of sentences relevant to the story. "I like *aspect of story*, due to ____." Maybe some speculation on what will happen in the story. Or talking about a character they liked. Or something that could be improved.

Review we would delete would be of the 'This is the best fic!' or 'Please update!'. Something short and pointless and which could be arguably applied to most fics anyway without any noticeable difference. Beta-style reviews (or maybe just long, in-depth reviews) are certainly not expected though.
