So what exactly was her "fake" grandfather doing by having sex in a ritual? Someone mentioned earlier that it was her real grandmother that he was having sex with in the book. Were they trying to get pregnant in case Sophie was killed to continue the bloodline?

- Losing the inner cryptic and using the inner ones password to open the outer cryptic was strange to me, but I can see how those who haven't read the book wouldn't pick it up.

- Using the 'library card' -- ahem -- internet ready cel phone to get the A. Pope clue was a bit dumb-down. I liked the interaction of the librarian when she recognized Langdon.

- Interrupting his book signing rather than pulling him out of bed in the middle of the night. I thought the latter was more dramatic.

- Showing Teabing over the body of Remy... it was too early to show him. Couple that with Sophie's seeing the dust tracks of the shoeprints and cane marks and the twist is ruined before it happens.

- Silas getting shot right there rather than being found dead in the park.

- The omission of her brother at the end and the gathering of the 'priory' folks.

- I was really upset that Aringarosa told the council what he was going to do with the money. That whole rearrangement made me cringe and it didn't help the story.

+ I loved the flashbacks in history while Langdon and Teabing were talking.

+ I also liked the 'effects' that were used while Langdon was solving the anagrams and the cryptic.

There is a lot in the book about the sacred feminine and how its worshipped.. dont remember the details, but its a worshipping thing fun orgy all in one

That was a weak point in the book, made even weaker in the film. The heroine's grandfather, as head of his Order, was expected to participate in a sexual ritual with his mate (his wife who was living in England but was assumed dead for security reasons) as part of the sacred feminine celebration. When Sophie accidentally saw him in action, she was "schocked" that her grandpa would indulge in such rude behaviour and cut off all relations with him. [This is not very realistic as no Frenchwoman I ever knew was ever shocked by any form of sexual propensity in her family, as far as I can tell.] In the book, her "schock" was alleviated when she found out her grandfather was actually having sex with his own wife, whom she had assumed was deceased, and not with "another woman" [more improbable, puritan American moralizing hogwash here]. In the film, the whole thing is swept under a carpet of mystery, secrecy and prudery, so that it can't be assumed that a descendant of Jesus Christ would indulge in any form of sexual impropriety. We know Sophie sees "something" that may be a sexual ritual but no mention is ever made that her grandfather is directly involved, which makes anyone who didn't read the book wonder endelessly what the hell got the girl's goose up for 20-odd years. When it is revealed that Sophie's grandfather is only adoptive and not biological (not in the book), this is somehow supposed to alleviate her shock at whatever we thought we were looking at that we can't be sure of because of the complete whitewash job in the script. And the revelation that her grandmother is still alive is still a completely befuddling - and almost comic - mystery since we don't know (and the film doesn't tell us) whether that woman is supposed to be her adoptive grandfather's widow, or the surviving mother of one of her deceased biological parents. By this point, most viewers who have read the book have seriously ceased to care one way or another and only think of heading for the john, getting their money back or punching Ron Howard in the face.

The reveal of Teabing as the Teacher (?) responsible for killing Sophie's grandfather is very well done.
Why is exactly is Sophie "shocked"? Everyone gets a shock to find their parents still have sex so maybe finding her grandparents do is a double shocker, but as far as I can see she saw "something" like her grandfather having sex with his own wife in a sexual ritual.
I noticed the second Cryptex wasnt in the film. The bit where they find about "A Pope" using some guy's mobile in the film seemed very dumbed down.
