To all those making movies in the "teen" genre.. THIS is how you do it.
The story is awesome. The actors can actually ACT. There is tons of action. While there is an underlying love story element, it doesn't overpower the movie, isn't the core of the story, and viewers aren't assaulted with gag-inducing lovey dovey lines.
This is a movie that guys and girls can both enjoy. The actors aren't devoid of emotion (sorry, Twilight saga, I love you, but for some reason, the directors are telling your cast they're limited to two facial expressions, max) and are actually quite good and were well cast.
It does deviate from the book a bit and there are parts that were left out or changed which disappointed me a little, but overall it was pretty faithful. Number Six steals the show.
It's too bad...
