For me, this sequel was a decent continuation of the original. It was based on the same concept as the original with some minor additions.
The story was simple and light hearted just like the original, the screenplay was decent, the direction was decent, the animation was unique like the original and the voice actors did a good job. The thrill elements were embedded nicely in the story which makes this normal story little bit enjoyable.
But to be honest, I think this sequel was unnecessary as it was underwhelming if we compare it to the original. Overall, this movie was a decent entertainer.
