If you like the V airing now, you should really check out the mini-series that started it all.
If you scroll down on the page, you can get the first and second mini-series, plus the full hour-long series for $30.97:
From Amazon: In its day, V was a monumental event that for one generation remains a pop-culture touchstone. ... Visitors who claim to come in peace are revealed to be nothing but human-looking reptilians on human conversion and conquest. As in the dark days of fascism, some collaborate with the enemy; others form the resistance.
At the time, the epic scale of this production was unprecedented. Those 50 motherships that hover over Earth's major cities anticipate Independence Day by more than a decade. The special effects and makeup are still awesome.
