I've read several complaints that the aliens "The Silence" are somehow derivative of the "Gentlemen" from that awesome nontalking episode of Buffy the Vampire Slayer.

Makes me want to kick someone.

Did someone of note say this first, and others are copying? Or are there just that many people who see a monster in a suit and start twitching.

Gentleman=Exaggerated rictus grins
Silence=no mouth
Gentlemen=Constantly moving in weird, mime like ways
Silence=Usually perfectly still
Gentleman=Suits, with pocket square evoke elegance.
Silence=Suits evoke MiB, faceless bureaucracy
Gentleman=Brothers to Nosfeatu
Silence=Basically a Gray Alien in a suit.
