The “How to Train Your Dragon” series has become big business for Dreamworks Animation, who’ve gone beyond movies to deliver video games, books, and multiple television shows that detail the epic fantasy world where humans and dragons are learning to live with each other, often heroically. That’s all well and good, but the real magic of the franchise is found on the big screen (the biggest, of you can find it), with “How to Train Your Dragon: The Hidden World” the most awe-inspiring and thrilling of a trilogy that began in 2010. Closing out the saga of Hiccup and his pal Toothless, writer/director Dean DeBlois gets a little sentimental with the second sequel, but his aim is to end things as excitingly as possible, delivering a healthy amount of action and discovery, along with plenty of Viking tomfoolery. While lacking the sweep of the last chapter, “The Hidden World” makes up for the loss in other ways, with DeBlois crafting a divinely animated, supremely felt effort. Read the rest at Blu-ray.com
