I noticed a review that has things that aren't complete sentences, it would work if they had them listed with bullets or dashes. Is it the job of the editor to add in a missing word to make it a complete sentence? For example, adding "It's" to the beginning of the sentence would make it complete if someone said something like, "porous and hard to clean". To me, that isn't a complete sentence but would be okay in a listed format:
-porous and hard to clean
Like how some of us list our pros and cons.
Or am I wrong? It just makes more sense to me to add in the word "It's".

I hope I'm making sense here less
