not yet mentioned:
-The Thin Man series (Nick Charles's mustache is the GOAT. Also, heavy emphasis throughout the series on the three pillars upon which I have built my own life: (i) whimsical abuse of alcohol; (ii) solving crime as a hobby; (iii) tuxedos. Song of the Thin Man is somewhat weak but much shorter than any Lord of the Rings movie)
-the Antoine Doinel series (a lot of people are kicking themselves for not mentioning these. Bed and Board was not great but still better than any of the Oceans 11 movies, which, come on)
-Faces of Death (caveat: I'm not sure whether the movies in this series contain different content or are just the same content presented in different order (I strongly suspect the latter), but if you mix grain alcohol with mountain dew and watch these as they were intended to be viewed by the auteur(s?), you will not walk away disappointed or at all)
-Matrix (I did not like these, but they are much loved by the types of people who I imagine enjoy posting lists of movies that they like on internet message boards, so throwing it out there for some bozo to expound on so I can respond by saying "How dare you compare Keanu Reeves with Marlon DePacino, you uncultured bozo" or whatever)
-Rocky (all great, except the boring first one where [spoiler alert] he loses and the one where he goes back to Vietnam)
-man with no name (I literally got punched in the face for coming back from Blockbusters with For a Few Dollars More circa 1988, so I may be overrating these movies out of wounded ego. Sorry, they were all out of A Fish Called Wanda, you big jerk)
