She and Her Cat
The OVA that started Makoto Shinkai's accession to the throne of melancholy and visual perfection. While being the first one, it is on par with his later works.
How much emotion can you pack in a 5 minutes long story told from a perspective of a cat? More than to a typical blockbuster movie. It is quite surprising how little is sometimes more than enough. Slight symbolism and emphasis on mood are trademarks of this masterpiece. In fact it is more like listening to a classical piece of music than watching a movie. Yea, something like Merry Christmas Mr. Lawrence by Sakamoto Ryuichi, it sets the mood and offers you a hand. It is entirely up to you to take it and regard those emotions as your own.
Makoto Shinkai is well know for the visuals of his movies. It is for a good reason. This monochromatic piece of art looks stunning. The decision to make it black and white was absolutely genius idea, more colours would only distract you from what it tries to tell. There are not many movies that look better than any of Shinkai's works and this is more than true even for his first one.
You don't know what to do with those 5 minutes of your free time? Check this OVA. It is well worth the time and if you like it, try Shinkai's other movies. They are all excellent, if a bit similar.
