Although not with the same sophistication as Tarantino, I like the nods at graphic novels, spaghetti westerns, and Jame Bond-movies. The '60s plot (cathing Nazi scum still at large) is interesting. It reminds viewers about the complicit role that other countries, like Spain, had in the Nazi agenda.
It is true there are some totally unrealistic scenes, but those don't truly hinder the goal of making people remember the horrors of Nazi persecutions and the Holocaust.The characters often mention that, unless they do act on bahalf of all those victims, it is as if victims had never existed.
Bottom line, depite the flaws, I enjoyed watching it (in Spanish).
