Originally the bright B3 star’s powerful radiation & stellar winds most likely swept aside any rubble in the proto-Siran proto-planetary disks that could’ve potentially made planets given enough time.

Not only that but the B3 star (Sirius B now nicknamed the Pup to Sirius A’s dogstar!) then became a red giant – perhaps even supergiant star and irradiated the already implausible hypothetical worlds even worse.

I did see ‘V’ years ago. I thought it was very dumb then – & my opinion hasn’t changed now. The sex bit oddly I don’t recall. But wish I did!

As for “well they came from somewhere else & just lied about their home” idea – yegods! If so, they sure could’ve picked a less suspiciously silly star to claim homeworld from y’know!

The rest of the routine was just as much a gag. They weren’t stealing water; they were openly refining Heavy Water from Lake Michigan (the “chemical plant” that figured so heavily in the original series), and as well teaching hydrogen technology, fuel cells et all, to the humans. Which was also an end run; the Visitors actually didn’t have practical small fusion engines, and the fuel cells they were helping the humans with were actually the height of their own technology. The spaceships, of course, were largely hollow props.

In the intent beyond the intent, though, the Visitors were neither invading nor stealing water or foraging. Instead, they’d annoyed a vastly more rapacious race that was on its way now; what they were trying to do is kick Earth into at least marginally competent fighters for an interstellar war that was going to involve Earth whether the Visitors visited or not.

The danger with trying to make something like V make sense, though, is that you really can’t. Once you start into trying to make logical explanations, all you really do is make the deeper questions more obvious. Better to say nothing and get on with the story.

Speaking of V, unless they can do something different and original with the concept – and they won’t – the series should not come back.

How about a series on non-human aliens who are not out to get us, or even give a flying fig about humans and Earth for that matter? That’s probably the real case anyway, but it doesn’t sell advertising time, does it?

And don’t forget how incredibly strong they were, unless they were trying to break down a flimsy closet door. And I also remember near the beginning of men in black, they’re chasing an alien who is running over buildings like they were lincoln logs… and then the alien commits suicide by jumping off a building.
