It's not bad, it's quite entertaining, but it has several weak points, mainly the animation of the dance scenes and the terrible Spanish. In fact, I think the short flamenco duet that was used as a teaser is 10 times better than what appears in the movie, and it wasn't great either. However, I think the shading and art style in general is a bit more polished than in the anime. And the story follows the same line that we already saw in the anime, so on that side I have no complaints. In short, it's not bad, but it could have been better.
