Everybody else has a Top 100 list on Letterboxd, so so can I.
These are not necessarily the "best" movies I've seen (although to be sure, many canonical classics are on the list), but instead the ones that I have the strongest gut reaction to. These are the 100 movies that make me love movies.
In alphabetical order, because honestly, all of these are number ones. (actually, I take that back; 2001 is #1, Brazil is #2, and all of the rest are #3s)
