Seen it in 3D IMAX . It was wonderful. Definitely a good 3D. Soaring through clouds, around mountains and over water: diving, twirling, coasting
The characters were perfect. The relationship development was overly impressive by far. Every last one of them played their part to perfection.
The male twin was spot on, and event though his twin sister looked different, her personality fit. I like the red haired twins :). It worked well.
Hiccup's love interest may not have been blonde, but they do look adorable.
The chubby friend may be more intelligent than his cartoon counter. It was the perfect group of friends.
A must see, highly recommend
