I have to give How to Train your Dragon 9/10. I may be somewhat generous but you will understand once you see it. Dreamworks Animation absolutely deserves this mark. This is the best animated movie I've seen in the last three years.
I find it hilarious compared to Avatar . I find the movie is so much better in terms the storyline and the character development. The script was fantastic. Note: I did not watch it in 3D because I despise 3D in almost all movies.
Nevertheless I found the visuals effects to be remarkable even without the 3D. It is so good, it feels like Pixar HAD to be involved LOL. Is it possible that Dreamworks has finally figured that out? In many parts just like when I saw UP (my favorite 2009 movie), I felt like it had to be written by animal-lovers because the writers show so much much comprehension on building the bonds between a man and an animal.
This bond between the kid and Toothless makes the movie so believable and I simply savoured every minute of How to Train your Dragon. How to train your dragon is brilliant and smart. My favorite scene : Toothless trying to force a smile. This movie is a great movie for young like old. I highly recommend it.
