* CompleteMonster: [[spoiler: Dr. Meddows in the 1988 remake is a military scientist specializing in bioweapons. He's inadvertently responsible for developing the Blob by sending the satelite and the proto-blob sample in space, where it mutated before it fell back down on Earth. He didn't expect it to develop into a ravenous, all-consuming monster, but is [[JustThinkOfThePotential more than pleased at this development and the military potential]]. He cordons off the town where the blob has started its spread so he can test its killing potential on all the inhabitants and to perform further experiments on the survivors. He's even willing to sacrifice his own men to further his goal, as he orders the sewers blocked off when two of the heroes and one of his men try to escape from the pursuing Blob.]]
** The blob in that remake may count as it has the capacity to think (as in setting traps and taking its time).
* DawsonCasting: In the time-honored Hollywood tradition, 28-year-old Steve [=McQueen=] plays a teenager.
* EarWorm: The theme song to the original movie, which is also a case of LyricalDissonance, as it's an upbeat, catchy pop number of the popular style at the time about how the Blob will eat you if you're not careful. Hits new heights when seen with the original's Saul Bass-inspired opening credits.
* HilariousInHindsight:
** The first movie's assurance that The Blob will not be dangerous "[[GlobalWarming as long as the Arctic stays cold]]" may be inadvertently funny to modern viewers.
** According to child actor Michael Kenworthy (who played the cheerleader's little brother in the '80s remake) the boy who played his friend (Douglas Emerson) had a typical StageMom: she was always there badgering director Chuck Russell into using her son, demanding he would have more and more screentime. It's amazing that she permitted the events of the film to take place [[spoiler: (seeing as his character gets eaten trying to escape the sewer)]], and what makes it funnier was the fact the movie was not initially very financially successful anyway.
** Another thing potentially funny: during the theatre sequence someone is seen laughing in both films. In the 1958 movie, while the Blob is attacking the theatre patrons some crew members are seen laughing in the background. In the 1988 remake, while the cheerleader saves her brother and his friend there is a sequence where they run across the projection screen and the boy in the yellow sweater is supposed to be terrified but you can tell he's laughing.
* {{Narm}} - A mild variation. While the remake is scary, there are times where the Blob looks a little.....too pink.
** This could actually be unnerving to some people, because if you look in some scenes, you'll notice that it appears that the Blob has veins, so it gives it a more "fleshy" appearance, which IS pretty gross and disturbing. It was most likely done intentionally. Why? [[FridgeBrilliance Because the Blob dissolves things like acid, so it looks more like a living stomach!]]
* OneSceneWonder: Olin Howlin as the man who first gets the Blob stuck on his hand. He's honestly a little ''too'' good at portraying the pain of the experience.
* ParanoiaFuel: The Blob can come out of anywhere and glue itself on and absorb you, which means you're practically dead the moment it touches you.
** The 1988 remake makes it even worse. ''The Blob has tentacles to grab you if you try to run away from it.'' Oh, and it isn't slow moving like its '50s counterpart. This Blob is ''fast.'' Good luck sleeping tonight...
* SoBadItsGood: The original, by modern standards, is not in the least bit scary and so clichéd it comes out as this.
* TheyChangedItNowItSucks: Although the visual effects were ''very'' impressive in the 1988 remake, a lot of people thought the Blob was actually less scary when it was turned from a natural space creature rooming the galaxy for things to consume into a government project gone wrong.
