I prefer films that leave you thinking about them days, weeks, months, even years later. I like films that the very thought of them hits you in a certain way. Wim Wenders' Wings of Desire is one of those films. The thought of it brings a smile to my lips. My brain is flooded with images, quotes and thoughts.
If you haven't seen it yet, try to seek it out. Don't read anything about it beforehand. Trust me. Let me know if you fall in love with it like I did.
