Angels and Demons

The Book 10/10.
The Film 3/10.

This is just another reason Hollywood should keep itself to itself. The film adaptation of Dan Brown's masterpeice was a huge let down. With numerous minor differences and multiple major differences it was, quite bluntly, crap.
The main scapegoat (Maximilian Kohler) is omitted.
Cardinal Baggia is branded but does not drown.
The antimatter cannister has interchangeable batteries.
Robert Langdon never visits CERN.
The antimatter cannister does not have a 24hour timer, but a bar timer.
Langdon is not in the Papal helicopter with the Camerlengo.
The Illuminati Diamond is replaced by two crossed keys.
The Hassassin never kidnaps Vittoria.
Langdon and the Hassassin never have an underwater duel.

And those are just some of the differences that cause the film to get such a low score.
