Strong points that I loved:

- Good actors (all of them.)
- The FX are magnificent
- Colours, contrasts, saturation: the photography of the film
- The costumes
- The moral: you have to keep dreaming even when if you are an adult
- The objective: to denounce school bullying


Weaknesses

- Sometimes a bit long for really futile things
- The ending is a bit too open for my taste and doesn't explain a quarter of the drama.

Good drama but not the best.
