Book of Secrets is a better film than the original, but that's not saying much. The plot is more interesting here yet more of the same, the talented cast is bogged down here by a dumb plothole involving the City of Gold or whatever, and the excitement gets more and more generic as the movie goes. Still, this is a fun ride with moderate thrills and the occasional low-key gag. If you're looking for a fun, dumb, generic summer movie, this is it. If you want a serious adventure film with a fresh style, some great acting, fast-paced action, and sly humor, this is dull cinema.
