The movie was just that a movie based on an awsome book while I think they did an okay job there will be things that you will be unhappy about ie the world cup, lack of winky, the obsticles in the maze, the lack of explanation about a few things that if you hadn't read the book you wont know, etc.
however I will say that of all the movies it is the best so far and I think the next one will be the best.
