I'll admit it's a little strange, actually it's a lot strange, but it is so sweet in the way it goes about it that you can't help but enjoy the ride. It's a unique look at love, in a great setting without the downer of asylum documentary type scenes. The hospital is used to further the story, not to create conflict. I love how each person has their own story and personality. The opening scenes may through some people off, but it's deffinately worth it to stick around. :)
Couldn't figure out how to add a link, but if you search it on Youtube it's easy enough to find.
