Very hard to pick one but The Wind Rises has a special place in my heart (tbf most Ghibli movies do). First of all, I watched it when I was very young and forgot about it so it was like rediscovering something I've almost forgotten. Second, I'm in and engineering program and know a bit about planes and such so I could relate to the MC. Third, I love the more adult feel of it and the Shakespearian romance. Lastly, it does all the usual Ghibli stuff great like animation, ost and wholesomeness.
