I usually agree with Zaiger but I'm going to play devil's advocate on this one.
Movies and TV are first and foremost about entertainment, no question about that. So if anyone says the primary reason for making a show is to make a
warning, I'd have say, that's not the reason entertainment is made, it's made to entertain.
Having said that, I think some movies or TV shows can contain messages that can act as warnings to us. One example that comes to mind, is a movie
called "The China Syndrome" www.imdb.com...
about what could happen if a nuclear power plant had a meltdown. 12 days after
the movie was released, there was a partial meltdown at the three mile island nuclear power plant! I think one of the unintended consequences of the
movie was a warning and it so happened the warning came partially true.
A couple of other warning movies come to mind, Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb
and even though it's a comedy I think it's a warning about what can happen if doomsday machines are
Similarly I think "War Games" www.imdb.com...
was partly a warning about what can happen if we give too much control of our
nuclear arsenal over to computers.
Now as for "V" being a warning, I see an underlying warning in the show. We've got crackpots like Steven Greer claiming that aliens are benevolent
and won't harm us, and some people seem to believe that garbage. My best guess is that aliens (if they exist) would, like other human individuals and
other nations have a range of attributes, some are more good, some are less good, and some can be evil. And that may be true for an entire species or
culture of aliens, or of the aliens individually as well...and here we have the parallel example in the V series, where some of the aliens are
"good", namely the "fifth column" who disagrees with the evil intent of the leaders.
The warning about contact with aliens was given to us by Stephen Hawking, that in our history on Earth when more advanced cultures have come in
contact with less advanced cultures, the latter haven't fared well, so we should heed that warning and not make an active effort to try to contact
more advanced ET cultures before we're ready.
Now as for whether there's anything more specific we are being warned about, no I don't think so. No impending disclosure, other than the continued
release of FOIA documents after they become declassified etc. But I do think we need to hear the warning that not all alien contact may be with
benevolent species. The warnings about aliens could take much longer to be realized than the warning in the movie "the China Syndrome" which only
took 12 days, but I think we should consider that some movies do pose possible scenarios that go beyond their pure entertainment value.
But entertainment is still the primary purpose, and not any warning.
