First of all, Pitt's accent ...

Rating: 1/10 (30 May 2016)

Texas? Brooklyn? Midwestern? Couldn't tell but whatever it is irritated me greatly as an affectation.
Then there's both plot and story - not so much as plot and story (fantasy is fantasy) but their presentation, which struck me as pretty much being on the same level of affectation as Pitt's accent.
Same with script, cinematography, characters, soundtrack, acting and anything else I may have left off.
Now I can see how one could see this as a ridiculously off the wall parody of a war/cum spy movie but, as such, it just irritated me - neither plot nor story made sense, none of the characters were engaging and none of the 'bits' - like the German officer trying to negotiate medals, position and pay for allowing the bomb plot to go off - worked. For me.
Given the movie's success and rave reviews, mine is obviously a minority opinion. Which is fine and congratulations to all of you who enjoyed it. Just as I found it a weird exercise in slightly ugly pointlessness, it is fitting that if it does work for others, it works. That is the nature of any work of the imagination, that both viewpoints are valid.
