An entertaining film, but rife with historical inaccuracies.
I took it as a comedic farce, but it did touch upon the atrocities he committed.

Hollywood does not make films that are completely accurate... ever. They always change the details for various reasons. The same can be said of most the history books being taught in public schools. But this film does a better job of capturing the spirit of the situation than most Hollywood creations.
The biggest one is that Beria wasn't executed until the following year.
