Air: The Motion Picture (2005)

The plot is very similar to the actual anime with a few differences added.

I am noting going to spoil the plot of the movie but I can say despite the film having an alternative take on the series even if I don't agree with everything this movie did I still enjoyed the story telling of the movie itself which is the plus side.

The only downside I thought was that the animation in comparison to the actual series was low in quality.

But other then that. It's a nice film
