They should have left “V” alone...remember they revamped it after the pilot because it looked like it was “disrespectful” to our beloved OFUHRER.
The writing has not been as good as it could be. Ive seen better acting in some of my projects at the local film school. Unfortunately, I was hopeful..now just disappointed.
Part of it is that an alien invasion doesn't lend itself well to episodic television. It quickly becomes the same thing week after week. A lot of good SF concepts fail on weekly tv because the premise isn't deep enough to return to week after week. Stuff like 'Terminator,' for example.
Some SF does lend itself to episodic tv (Star Trek, Stargate, and others) because you can have the main characters go to other worlds and interact with aliens on their own turf. It's just a bit deeper than an alien invasion idea.
