Hollywood always seems to be on the look out for a unified villain that haunts our great American heroes from film to film, TV show to TV show. The Cold War was great for Hollywood because it delivered them the Russians. Then, there was a confused period where there was no unification of villains and every movie had to have a completely different villain. Then, Hollywood slowly started to place Arabs, Persians, and Muslims in general (often without really being able to distinguish these groups) as their "unified" bad guys. Problem is: some people started pointing out that this was fairly racist. So, the push for the unified villain somewhat moved on (I mean, the threat of being racist is not going to scare away all of Hollywood, I mean, Homeland is still on the air, right? Is it getting any better? I stopped watching).
