I think of myself as a film buff based upon a few different factors.
A) Could I make several recommendations to others for what to watch across multiple genres and interests.
B) I watch plenty of films outside (sometimes
faaaarrr outside) the Hollywood blockbuster type films - so that I can make informed recommendations to others, or at least hold a somewhat intelligent conversation about them.
C) I critically examine and deconstruct the films
waaaaay beyond "Did I like that? Y/N?"
- Did I like the screenplay irregardless of execution?
- Did I like the cinematography?
- Did I like the score?
- Were the characters remarkable? Could any random actor done an equally fine job of portraying the character? So, this was more about just telling the story, then?
- How much did it cost to make this?
- What revenue did it make? Is this above or below what I would have expected?
- What other films did the director make? Have I seen those? Can I draw comparisons between these films?
- Is this a remake or derivative? Have I seen the original?
- Etc.
D) If you regularly visit IMDB, Variety, TheHollywoodReporter, Collider, BoxOfficeMojo, and The-Numbers dot coms you're probably a film buff/junkie.
E) And finally, I try to stay abreast of upcoming releases, again, not only just the big Hollywood pieces, but also of the small indie films that perhaps picked up distro at film festivals.
