Oldboy
amazing movie. the ending was the best personally because i wouldn't have ever expected that, plus it being an ending that would change everything about the story was very impactful. one of the greatest acts of revenge in cinema in my opinion and it was the perfect one. nothing could have prepared me for that. and the vibe of this 2003 movie was awesome, pacing perfect and there was not a single boring scene, it was very well balanced. 10/10
