Saw this Friday night. Pretty average. The first half drags on but the second half is very thrilling and has some spectacular moments. If I had not read the book I think I would of loved it, but knowing the story and how certain events unfold I was disappointed. Also, not a film you watch for the acting. Has to be Hank's worst performance, but the character of Langdon in this sequel/prequel is more 'hands on' he was in DaVinci so I suppose that could be a factor, yet he's still very watchable.
Also, did anyone else notice something in the background at the Vatican Archives which looked a bit like the Ark of the Covenant, or did I just imagine it?
