Class: Andrew McCarthy as 80s quintessence

I just saw the movie "Class" for the first time (how had I missed this before??). I discovered that it contains many interesting elements that are dispersed, diluted, echoed and reseeded in many similar films over the next few years. The genre is 80s teen/Brat Pack--could this be the ur-film in that category? I have started a table for comparison purposes. It is by no means complete, so please tell me if you know for a fact that there should be another checkmark somewhere. (I only checked off things I was Really Sure about.) Note that "Class" is in the bottom row here, with checks in every single column.
