Damn, I had a longer reply typed up but the token expired and wouldn't let me post it. Anyway, here's the gist of it - I try to assess a film on its own terms rather than hold it up against a bunch of arbitrary Great Film criteria. That way, I don't dismiss a film because it doesn't match up to a cinematic ideal that it was never really trying to achieve in the first place. This is exemplified by your stating that Star Wars does not qualify as a great film for not treating the concept of warfare as seriously as Come and See does (besides which, it's not like Luke fighting for the Rebels is nothing but childish fun and games either, but that's a conversation for another time, I guess). This isn't significantly different from the hypothetical "pleb" who only likes simple Hollywood crowd-pleasers and writes off old/foreign/artistic films as "pretentious". Of course, this isn't to say that you have to like Hollywood crowd-pleasers, but you at least have to be willing to bend your expectations a little and be receptive to what Film A is trying to do rather than dislike it simply because it doesn't do the exact same thing as Film B or if it seems similar to Film C.
I find it funny though how off the mark you are about my whole film analysis and comparisons. Like when you said, "This is exemplified by your stating that Star Wars does not qualify as a great film for not treating the concept of warfare as seriously as Come and See does." Was it a straw man, or just a missunderstanding? Star Wars doesn't qualify as a great movie because it's content is shallow, and it's technical aspects, except for special effects, are not masterwork. Come and See was an example of a movie that dealt with it's subject matter (war) extremely well and was technically impressive too. You didn't read my post very carefully did you?
