Wes Anderson does it again! He populates a real-world setting with seemingly unreal character interactions, but this formula works every time! There is real art to be found here; but I do second what others have said. There is a blush-worthy scene involving (if not a bit humorously) sexual discovery between the two teen protagonists. It really isn't too bad, but fourteen and up is an appropriate age for audiences. Its hard to find a film that captures what it is like to be a kid again, during the awkward phase in life where we start discovering that we have real feelings and that they need to be confronted.
Definitely go for a artsy date night, but leave the non teens at home for this one.
