The art style is a bit different than the anime, but it follows more closely to the style in the manga. The animators took care in animating the scenes so that they're not simple, but exhibit emotion. It's definitely a breath of fresh air compared to the anime (no offense), since it has nicer and deeper aesthetics.
The music was my favorite in this movie as well; recommend listening to the OST.
The voice acting for Kikyo was done so well, it was delivered very well. Kagome as well. (You'll see what I mean when you watch it).
The anime tends to gloss over emotional scenes that may contain development, which I don't blame considering there aren't many words said between Inuyasha and Kagome in the manga to show how much they mean to each other. However, in the movie, it took care in executing their scenes when needed, which produced great results. I actually cried because of the softness and the way it was depicted.
The animation was very pretty as well and delicate.
Definitely a movie you can watch with non-Inuyasha watchers.
Overall, to describe the movie in one word: "precious".
