<SPOILERS> Here is a link to a review that sums up the film quite nicely. I'm probably going to rewatch this one, given how intense it was, I had to "avert my gaze" a few times. But this review is by some guy named Bilge Ebiri, titled "Let's Watch Some Nazis Explode".... https://archive.ph/114xj I've also seen several reviews make comparisons to John Wick, although I have to say the gore in John Wick pales in comparison to what we see in this film.

Edit: I'm about halfway through my rewatch. To be fair, there is no direct comparison that does this film justice, but I will say that it reminds me a bit of Inglorious Basterds combined with any of the John Wick films, add an elevated level of carnage and artistic merit. Indeed, the director takes great delight in creating situation so violent, so incendiary, as to render the viewer speechless. Another indirect comparison, though apt - would be the Die Hard trope. At the beginning of the film, the viewer is conditioned by virtue of other movies in the genre to imagine there is no way for the protagonist to survive, say passing through a minefield or being lit on fire, with gasoline, or being hanged. But survive he does, and so by the time the next hopeless scenario is presented, you say to yourself, "oh, this is survivable, our protagonist can do this!" In the immortal words of the Black Knight, "'Tis but a scratch!" Indeed, the protag's brutal, outlandish methods escalate to the point where, by the time the bad guys could simply gun him down out in the open they choose instead to flee, convinced perhaps of his godlike power. And we the viewer when presented with the next impossible scenario, are left with no other option than to believe it. </SPOILERS>
