Silly and implausible -- I'm all for suspension of disbelief but this had way too many absurdities. One little piece of idiocy -- how could a high-level academic supposedly qualified to do research in the Vatican archives possibly need help translating something in Latin or Italian? And the parachute concept is way beyond belief. But then the whole plot is beyond belief. The only reason I give this two stars rather than one is because the scenery is interesting. Otherwise a total loss in my view.
