Well, music is terrible and I feel like there's no need to discuss this.
Regarding the rest, I've watched all stages of anime countless times, comparing movie to it... it's clear that they were low on budget (lack of characters from the original anime, racing only on one mountain, certain races being changed from how they were in original... but then again, there's only so much you can do in real life compared to what you can do in anime...
Overall, if you put all the anime/manga backstory aside, movie is enjoyable and it's fairly fine (excluding the music), but this movie is no match to the anime in any way.
