(Don't take the order too seriously!)
Oh boy, that was a tough pick, but after some consideration I can happily present: the top 25 of my favourite movies of all time.
Please note that this is only a glimpse into my present mind. I'm a flexible person and nothing is set into stone, but at the present time these are the movies that I can pretty much watch at any state of my mood. Movies that will most definitely make me feel joy, anger, despair, melancholia, nostalgia, amusement, relief. Movies that will make me cry, laugh, feel helpless, keep me thinking, make me fall into a loop of self-reflection. Overall, movies that make me appreciate the wondrous world of cinema!
(I have to add, Before Sunset could be basically replaced by any other movie from this beautiful trilogy and you could also replace 'Spirited Away' with 'My Neighbor Tortoro!)
