No.
This movie should be watched only by fans in order to remember the story before watching the upcoming second season. Because creators had to put 13 episodes in one film, they didn't include important moments that are necessary to develop characters:
1) The movie DOESN'T show how the relationship between Eren and Jean was shaped during military training. Their conflict considering how to live and what to do in the world was shrinked to from-time-to-time quarrels.
2) The movie DOESN'T show a well done flashback about how Mikasa was saved by Eren, which gave the audience explanation why Mikasa feels strong for Eren. The movie only shows pictures of memories and Mikasa's inner thoughts about this matter. If a newcomer were to see this movie before finishing original TV series, he or she would be left with a lot of questions.
The movie is really fast paced. It provides a lot of action and less mystery about the world that characters live in. Their development was thrown away. And surely this movie was created to gain more money from fans (it seems that selling t-shirts, hoodies, coats, hats, figures ON EVERY CORNER is not enough).
I don't say that the movie is bad. But remembering how Gurren Lagann was recaped, especially the second movie, I conclude that creators didn't put much effort into production. Yes, the art is very good but only it.
Thank you for reading.
