This is an impossible question to answer

so i tried different things
1st: ask plex which movie i watched more often
-Jason Bourne
-Maze Runner: The scorch trials
-Resident Evil Welcome to Raccon City
Thats a hugely disappointing list
2nd i checked my physical copies (movies i watched often i usually buy 4k bluray versions), also hard to make a 3 movies list so i made 2 based on older / newer films (it's probably cheating but who cares)
Older movies:
-The Warriors
-The exorcist
-Se7en
More recent movies (post 2000)
-Black Hawk Down
-Dune
--Asterix et Obelix: Mission Cléopatre.
Those may not be my favorite movies but those i watched several times.
