Saw the film and enjoyed it, although I thought "Pirates of the Carribean" more entertaining. This film certainly captured the violence that must have been common during a naval battle. I liked both Jack & the doctor, and can imagine they had a very complex relationship in the books.   

OK - those of you who haven't seen the film - don't read any further.
SPOILER QUESTION ABOUT END OF MOVIE !!!!

What did the doctor say to Jack about the French doctor and the French captain that caused Jack to cancel the shore leave and pursue the French boat again ???   I had a hard time with the dialogue in the theater I attended. I got the general idea, but didn't understand the details ?? Thanks for any clarification.
