Its pretty clear its using racial stereotypes of minorities to paint white people as evil. I think thats why it turns alot of people off. While at the same time ticking off minorities because they use stereotypes like the Chinese guy with laundromat or Mexican with a leafblower.
The only really funny episode was the one one where they split up and went back in time and one group gave Civil War Confederate soldiers M-16 machine guns and another group showed up with the Ark of the Covenant and gave it to the Union to defeat the South in a scene stolen out of INDIANA JONES.
Hasnt been on in months and I dont miss it at all. I could take it or leave it most of the time.
