It is amazing how "How to Train Your Dragon 2" is able to expand and surpass its predecessor. The sequel is full of deep emotions that not only surprise and shock you to the core but gives the movie a lot of heart. It feels darker but for all the good reasons. It is more mature and more daring and in turn more satisfying and puts the series into high gear. Put simply, this sequel is a must-watch; the rare few times were sequel matches or one ups its predecessor.Five years have passed since the heroic young Viking Hiccup (Jay Baruchel) befriended an injured dragon and forever changed the way the residents of Berk interact with the fire-breathers. Now, Vikings and dragons live side-by-side in peace on the fantastical isle that has been transformed into a dragon’s paradise. But, as Hiccup discovers new unmapped lands, he encounters dragon hunters who captures dragons for a man named Drago (Djimon Hounsou) who is building a dragon army. His father Stoick the Vast (Gerard Butler) reveals that this Drago is actually a madman who is out to conquer the world. Hiccup thinks he can change Drago's ways and goes out to find him."How to Train Your Dragon 2" delivers in almost every aspect. Story-wise, it was darker but more mature. The father-and-son, Hiccup-Toothless dynamics we loved from its predecessor is back with bigger problems to solve in each. It dares to explore dilemmas that you rarely get to see in this genre while building upon on what we knew from the first film and that's great. By the end of the film, when everything finally unravels, we just couldn't hold back our emotions anymore. Visuals are a huge improvement as well. There were scenes were the dynamic colors just pop out and simply awed us in wonder. The old characters get an detailed face lift of their own too so that's that. We also have no qualms on the voice-acting and script. It had its moments drama-wise and comedy-wise. The only minor quibble we have was that the first few hour felt a bit of a stretch but that's about it; everything else was simply wondrous.Rating: 5 reelsWhy you should watch it:- another heartwarming and emotional tale- visuals are simply marvelous- it feels more mature and better than its predecessorWhy you shouldn't watch it:- the film had a bit of a slow start
