My first gripe about this movie is the title. I don't really understand why it's called Book of Secrets. It would have been more appropriate and more interesting ( I think) to call it City of Gold. That's what they're looking for but this time, it's not financial gain they're after...they're trying to clear the name of a long dead relative. Whatever if you ask me. Apparently that's important to these people though.
The acting is what you'd expect. Nicholas Cage really has pretty much every scene stolen from him by his co-stars if you ask me. He's just no the most interesting character and maybe I just don't relate to him very well. I am really surprised to see Helen Mirren in a movie like this but I guess it helps pay the bills. She's good in the movie although she's not really given much to work with.
Like I said, I didn't hate this movie, but I can't give it much of an endorsement (although I know that doesn't matter). Tons of people are going to see it and probably love it.
