The Blob is some scary shit.
Second that, the only image I recall from it was it seeping through the ventilation grates of a packed movie theater, but...
And of course there was at least three (five?) moments or sequences from
Willie Wonka and the Chocolate Factory. Let's see ... the boat sequence, the blueberry daughter, and the fizzy lifting soda chamber. "SAW for kids" (as Honest Trailers calls it) is actually a pretty appropriate epithet.
My biggest movie trauma, however, was the "army of PIGS!" segment from the movie
Willow. This utterly burned and biased any interest I have in the TF topic and long before I even knew the genre was a thing. (And yet, I'm thankful to
have such a traumatic bias on the matter.)
