Pretentious and Boring . Despite what the tag line promises, this is not an epic story of WW II's most dramatic mission. It is ridicuous to even suggest such a thing. At best this is a superficial recounting of a late war mission which turned out not to be not nearly as dangerous as it could have been. The bravery of the men who took part in the raid cannot be questioned. However, there are countless other tales of WW II that recount much more horrificly dangerous events than the one depicted here. The book simply fails to deliver. If you are looking for a gripping tale of the horror and heroism that defined WW II this is not the one
Output:
NEG
