That was my first impression–a sexual one. A bunch of subservient guys bowing to their leader…yum! (Plus, I found the white guy pretty sexy.) Then when I realized they were all black (and…uh, the same guy), I got why people might find it racist.
Personally, I think the creepiest part is that it’s the same guy, over and over. That’s partly why I found the Oompa Loompas so odd in Charlie and the Chocolate Factory (same guy, again and again and again).
