DreamWorks Dragons is an incredibly enjoyable TV series and is part of a fun universe of characters both in the films, TV and other media, and even at the end of season 3, the show has still not lost the foundations that make it so entertaining, however, there are soon to be some continuity errors dependent on the chronology of the series being between the first and second films.
In terms of timeline advancements between the two films alone, the second film has many differences to the first which are yet to be explained and accounted for in the first 3 seasons of Dragons, such as the way in which 'Dragon Racing' is so fundamental in their world in the second film and yet remains unmentioned in the series. Additionally, subjects such as the intimate nature of the relationship between Hiccup and Astrid in the second film have not been expanded or developed after 3 seasons of the series and there are still no elements of romance in their relationship. Lastly, although this has partly come to be in terms of the wingsuit Hiccup possesses, there are many technological advancements that remain unmentioned in the series, such as Hiccup's multi-functional false leg depicted in the second film.
Of course, none of these issues of chronology and continuity hamper the magic of the series at all, but I do believe it is important for the writer's to consider these issues when it comes to the future development of DreamWorks Dragons in order to prevent any loop holes and logic that could potentially create a block to full enjoyment of the series.
