While this movie is geared towards kids, there is plenty of fun for parents as well! and, as a Viking Age history buff, I was pleasantly surprised by some of the remarkably accurate details in the background. The rather silly horned helmets were cute and I could ignore them as "expected' by the general public. The dragons were by turns scary and adorable and the requisite lesson was not too heavy handed and directed mostly at parents. The animation very nice and the dialogue clever. I've never read this series of books as my kids are long past this age but I may pick them up to read myself and see if they would be suitable for my infant nephew when he gets a bit older.
