How to Train Your Dragon 2. Being a sequel of a much loved movie, Dragon 2 walks on the tight rope of maintaining the fun quotient of Dragon 1 and providing some new fresh ideas which can make Dragon 2 memorable. Movie improves in the stunning imagery and usage of 3D effects considerably. Dragons' flight scenes would be hard to forget especially by new kids in the audience. Characterization of humans and dragons both is done with much care. But it is hard to ignore the fact that fun quotient has been lowered and movie takes a darker way in second half in providing few key twists and turns. Burdened by high expectations, Dragon 2 falls short of being a milestone movie but dares to take new chances. The chemistry of our hero Hiccup and his dragon Toothless remains the strength of the story. I am going with generous 8 out of 10 for How to Train Your Dragon 2. It has its flaws but is very well saved by excelling in visuals and characters department. Watch it in 3D for full impact.
