With regard to "Friday," maybe the most remarkable thing about "Boyz N the Hood" is how much more Ice Cube was able to do with this kind of material than Singleton, in two different mediums. Someone a ways back in the discussion alluded to the name-recognition of the movie's title as a reason to include it in the canon, but doesn't that have more to do with the Cube-penned Eazy-E song? I certainly don't think that there's a "Boyz N the Hood" movie, under that name or another, without the song (and Ice-T and the first NWA record, etc. etc.) coming first, and there are the movies others have mentioned that are better, or came earlier, or are otherwise more deserving of superlatives than this one--"Friday" certainly not being the least of them. (Though I'm loathe to forgive that awful "How's the writing of "Friday" coming, Ice Cube?" scene in "Straight Outta Compton.")
Anyway, I think the title actually does this film no favors, because it's got to share with one the seminal hip-hop songs, and one that depicts its milieu much more adroitly than the movie does. Put it this way: if you say "Eleanor Rigby," I'm not thinking of Jessica Chastain and James McAvoy before Lennon-McCartney.
