"V" is probably the most realistic of alien invasion stories because it relates to alien encounters that aductees and mystics have experienced. You can checkout some of this material under Reptilians, Grays and Marcabs.
Unfortunately, "The 2009 V Series" is simply a remake of the 1983-84 TV series. I was a bit disappointed because I had hoped there would be sequel.
The original "Vs" were like friendly Nazis from outer space and most viewers just loved to hate them.
I loved the orange uniforms and the sunglasses. Those reptiles were cool.
The present "Vs" look like religious cultists with all the answers. This is ok. Many viewers seemed to like this approach. The first episode got great ratings.
I love finding science fiction that strikes close to home. The original series I give four stars. The remake three stars.
