Not very good.

Rating: 5/10 (18 June 2014)

I was expecting this film to be great. I thought the first film in the series was, and I thought there would be both deeper story and more substance and further development to the characters from the first. Well, there definitely was an attempt, but I just thought the execution failed.
I try not to be too critical of movies, especially ambitious projects like this. But this movie felt rushed, and the way the problems and obstacles presented were resolved toward the climax also seemed rushed.
The music of this movie is a definite highlight, but I'm afraid can't make up for a lot of the sappiness in this movie, which is found heavily in Hiccup's familial circumstances and revelations.
This is definitely a wait-for-it-to-come-out on DVD or Blu Ray, if you're going to bother to see it.
