the death of Zara (Claire's PA) which felt gratituously cruel for a character who didn't do anything to deserve it - Hoskins had a quicker, less traumatic end! It felt out of place in the movie. No major problems with her being eaten but the way she went was just too nasty.

Mind you I'm a huge fan of the actress so I am biased there.
