Giving this an 8/10 rating
First off, try and watch the sub version which is Chinese, then the UK English dub, which I saw, has very good voice acting, with Bill Nighy and others, then you will have fun with this. I had a fun time with this Chinese/Spanish production about ancient China, dragons and Necromancers, and lots of magic.
It does look really colourful on a the big cinema screen, where I saw it, and the kids in the audience, here in London, did like it. I see low ratings because of the horrid American dub I fear, so I guess we got it lucky with our English dub, which really is good. The look really is Chinese for sure, and the main lead- the little girl named 'Ping' was to me, likeable more and more, once it got further into the film.
The themes are quite dark in places, but the dragons are great, and the style is good on the eye, some good humor too. I sat down and let it the beautiful visuals take me away. The version I watched was very wide, so there maybe an IMAX of this floating about. But really, watch the trailer of this first. But I paid my money, and liked what I watched.
