When you ask to be compared to Akira, even by bragging a bigger budget, you better brace for impact, because the comparisons are going to be brutal.
The film is rather bland on most, if not all levels. It is technically inferior to Akira in all areas of animation, totally lacking in grittiness, the characters are rather lame and lack any sort of real development, the soundtrack is boring, and the plot totally unchallenging.
It looks okay, but when you boast a bigger budget than Akira, it should at least LOOK better. It clearly doesn't, and the use of CGI and 3D models just enforces this.
And please, if you do insist on seeing this, try to find the japanese dub, as the english dub is atrocious. Paquin is especially horrendous, which makes it harder to root for the main character.
