In order to an audience better understand the later criticism of the material being reviewed, what should a review begin with?

A review should begin with a brief summary of the work, including a synopsis of the plot, major characters, and any other important details. This summary should be somewhat specialized to help support the specific critiques that the reviewer will be making, focusing on details that the critic will bring up later in the review. 

I’m just thinking something from the top of my head so it may not be much so if weathering didn’t exist, there wouldn’t be anything to break up earth’s crust naturally. so by assumptions, the rocks on earth would be larger than they actually are since there’s nothing to break them up into smaller parts.overall, i’m not really sure, but all i know is that it’ll mess up the rock cycle that we have now.hoped this .
