Firstly, it has a great plot: the idea of old and new worlds of technology mixed together in harmony is a new twist I haven't encountered before. Also, the idea of a community based this much on the internet is an interesting matter and very current. The charater development adds to the story: our protagonist is quite shy and afraid at the start, but turns out to be a brave and responsible boy at the end of the story. Another notable character is the grandmother which really ties the whole story together by her round attitude.
Moving on, the movie has a simple, yet recognizable character design. Its more outstanding art would be in the scenes going on inside of the internet; the creators have done some detailed work on that one, nice eyecandy and colorful art!
The sound is superb. However, I'm not talking about the sountrack which is pretty average, I'm talking about the voicing of characters. The voices of the different people in this movie is extremely realistic which is something I always look after in an anime.
Overall I really enjoyed watching this movie. I was engulfed from the first moment, and it is strongly reccomended. :D
