These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: The 2009 TV series has an unsubtle subtext of "Look after the natural world or it will eat you."
Magnificent Bastard: Torrence is possessed of a singular charm and wit that makes it easy to see why his men follow him so blindly.
Moral Event Horizon: In the 2009 TV serial, Torrence crosses it either when he orders Bill and Major Coker to be fed to Triffids to get them out of the way, or when he threatens to kill Susan and Lucy (two children) if Bill doesn't arrive at a solution to the Triffid plague.
The anti-triffid guns that feature prominently in publicity stills but rarely on screen in the 1981 series. The firing effect had to be done with Chroma Key, early-1980s Chroma Key at that. It looked more like a Doctor Who energy weapon effect than the Deadly Disc projectiles they were supposed to be, and the guns only got fired on-screen once. Averted by the actual triffid models, which look pretty good, even if the occasional close-up of someone getting hit by a stinger makes it very obvious that it's a foam-rubber prop.
