Average film with a fair few plot holes

Reasonably interesting premise, but a few things throughout just made it unrealistic.

One: It seems hard to imagine that there was that much booze and petrol around in wartime Europe

Two: The Germans were enormously incompetent at times, almost unbelievably so.
Like when they allowed Flame to escape from the bar when he went after the Gestapo boss.
Or when they took so long to kill Citron.
Or when they took so long to break into Flame's house.

Three: To the best of my knowledge, the Gestapo never brought partisans all the way to their headquarters to then stand them up in a truck outside and fire at them from several feet away.

Four: When Citron went to leap the fence, Flame was able to just walk away without any of the dozens of Germans there noticing. Ridiculous.

All of these took away considerably from the film, in my opinion.
