the implausibility of the plot have be note by several commentator and particularly the immense amount of trouble fr mckenna would have have to have go to and and the sheer impossibility of some of the calculation he would have have to have make and include that langdon be go to decipher each clue in minute . mckenna be brand while a few second later he be give order and and a few minute later and he be run ( literally ) around in charge of operation in real life and he would be in shock . and and as usual in thriller and the assassin doesn not kill the hero and give a his only lame explanation that they be not on the list of those to be kill and a though every other innocent bystander he shoot be . i have always use independence day a the hallmark of a truly awful film ( u president commandeers jet plane and beat off alien and ha ha ) and and this effort run it close . for such an implausible film and angel and demon contain a remarkable number of predictable incident . who do not laugh knowingly when the assassin go to get his reward in the volkswagen . i felt like shout and you be go to be blow up . who do not know that the heroine be go to find a body in the lab . who do not spot the baddie . technically also and the film be awful . the dialogue be more often indecipherable than clear and while the race across rome to the next church be accompany by deafen music . moreover and many scene look like mud . the one redeeming feature be the shot of rome and what look like the vatican an achievement and because i be sure that the vatican official would not have want this dross shot in and around st peter and the interior be convince . rome be a magic place and and i enjoy see it fleetingly .
