I agree with the sentiment that Avengers may not be the most sophisticated movie out there. Most people know this and would agree. But randomly calling attention to it to make sure people notice that you have a sophisticated taste is a little pretentious.

I had no idea this was a distinction. I just thought 'film' was what the British called them and 'movie' was the Americanism. We say 'I'm going to the see a film' rather than 'going to see a movie'.

In the case of a Marvel movie, it's almost more accurate to call it an animation, but movie covers all production methods.

Actually, that’s exactly how the English language works. There’s no governing body that matters who determines what counts as correct English. The closest thing is the dictionaries but those change all the time, in response to....people using words differently.

Similarly, we can't claim that centrifugal and centripetal forces are the same things just because more than 90% of the population uses the term centrifugal for both. Some words have specific meanings that don't change no matter how many ignorant idiots decide them mean something else.
