How convenient... (spoilers)
How convenient that the kidnapped cardinals were dumped at the markers to the church of illumination (or whatever it was called). They literally could have been left anywhere in Rome to die, but at least they were at the points Hanks was tracking down and in the order he was finding them so one could be saved and tell them it was going down at the Church of Angels. Although that only lead them back to St Pauls where they started so it really didn't affect the overall plot.
*and breathe*
Yes, I know films require suspension of belief. So i'll just have to let it go... like the guy with the gun not thinking about shooting the glass as the oxygen ran out.
Is this it?
