It's also about politics as well, and how we perceive them as well. Take a look at the new V series. It's set after 9/11 when we've become suspicious of everything different, where we value security, and those that aren't with us, must be destroyed. This new series once again explores the unknown, (and yes it sucks majorly right now because they need a writing staff that's more qualified to do justice,) but at the same time it explores how our ideologies are. Think about this as well, charismatic and "peaceful" beings who want to share with us their tech and heal us. It's also about religion. The old series didn't have a priest who was questioning everything that the V said. That's what makes this series so good, is that it has more depth to it then the original series. Plus the role of Anna, she has a hidden agenda, and while I am a democrat, I can see huge allusions to Obama and his presidential reign. The old series was directed more towards the whole Cold War era, in a time where we didn't know where we were going or what we were doing. In this new series, we have 9/11 and terrorists and sleeper cells.
