Doesn't stand out, but still worth seeing.
The soundtrack was amazing, the fact that Liam Neeson's voice was in the American version was very cool, it had the classic nature themes of Miyazaki's other works, and the animation and general art direction was great. Although the storyline was touching, I found myself getting kind of bored towards the middle. (I also remember being kind of concerned at just how happy everyone seemed to be throughout the movie.)
I say watch it, It is worth seeing at least once.
