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, the majority are canonical classics), but instead the ones that I have the strongest personal gut reaction to. These are the 100 movies that make me love movies.
In chronological order, because honestly, all of these are number ones. (no, I take that back; 2001: A Space Odyssey is #1, Brazil is #2, and all of the rest are #3s)
