The books actually ARE canon... they came before the movie. They are just a different canon, so please everyone keep that in mind.

I do think that the constant adding of dragon species is not a great idea. However, we are getting some new info about old ones. For instance, before HTTYD2 we did not know that Nadders have a fantastic sense of smell. Before HTTYD2 we did not know that Zipplebacks could use that flaming wheel technique. We are getting new stuff about the older dragons, so I'm happy about that.
