First of all, in order to better understand the movie and it's story, let me explain, how you should watch the Series so far.
Long Story short, after the Grand Magic games Arc which finishes with Episode 201 or Fairy Tail (2014) episode 26, A Gift (Okurimono), watch the Fairy Tail OVA (2016) Episode Fairie's Penalty Game (Yousei-tachi no Batsu Game), after it watch the Fairy Tail OVA 6: Fairy Tail x Rave, then it is recommended to watch the short Prologue of this movie first and only then the real movie. If you watch it some other way, you might miss the full Enjoyment of Fairy Tail.
Now the Story is great, Events take place after the Magic Tournament, The Fairy Tail guild has restored it's former Glory, they are back at their original HQ.
Our beloved characters are introduced to a new character, Eclair, a slender young woman, who is dressed in outfit reminiscent a traditional Indian Sari.
This already let's us recognize, that Eclair is some kind of Priestess, and in deed, our Phoenix Priestess has touching story to tell after which she gives a quest to the Guild, and Fairy Tail goes to another Adventure. In Veronika, there is real Evil hidden away which has the power to destroy the whole world, yet many evil Magicians want to unleash that power, not knowing the real Truth, hence our Guild fights to save the world.
As expected from the series, Art and Soundtrack are outstanding, like always. We get the Typical OSTs and funny Fairy Tail fan service moments, which unlike in other Anime, makes this Anime Great.
This movie is a great choice to spend an evening enjoying a Movie.
WATCH It!!!
