What would it be? I'm going to recommend one that you guys probably don't know (better than telling you to watch The Matrix).
Im Juli
A German movie with a big heart. I usually compare them with movies like Garden State and Amélie. I guess it's a romantic and funny road movie.
Daniël, a German math teacher travels to Turkey because the girl Juli made him accidentily believe he'll find his true love there. Before he's out of town, guess which hitchhiker he picks up. Juli.
Try it (don't forget the English subs)!
