Movies that are very different in style but I'd consider almost perfect movies for what they are in their respective category:

-I saw the devil (best cat&mouse type thriller I've ever seen)

-The Raid 2 (probably my favorite action movie)

-Spirited Away

-Train to Busan

-Batman trilogy (Nolan)

-Headhunters (2011)

-Oldboy (original Korean, NOT remake)

-Your Name (2016 anime)

-Edge of Tomorrow

-Looper

-The cabin in the woods

-Arrival (2016)

-Dr. Sleep (Director's cut)

-Donnie Darko (Director's cut)

-Pans Labyrinth

Probably some more but these are my favorite ones in my Blu Ray collection. Didn't include Shawshank redemption, Heat, the Godfather because everyone has these on their list and they are obviously A tier movies
