I saw this in the cinema, I was in secondary school and wrote an essay on this film. If I dig up that essay I'll post it here, but for now I'll relay some of what I remember.
> The messy editing, they just skip right through the dragon growing up.
> Pointless scenes cutting back to the bland villains sitting around.
> The final battle where I think dragons flew around and stuff happened.
> John Malkovich striking a painting at the very end, revealing an evil dragon.
Also this had a videogame on the Xbox 360, Alex Rider got a DS title.
2006 was just the year of bland films based on books getting videogames.
