By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.

Where Scream introduced "the rules" of the slasher as a means to break them, its sequels built a box that became increasingly constrained by lore and meta commentary. This pushed the film series farther away from Woodsboro — to college (Scream 2), to Los Angeles (Scream 3), to New York (Scream VI), getting to a point where Final Girl Sidney Prescott (Neve Campbell) was no longer the hero, but either a supporting character (Scream 4 and 5 — which was confusingly titled Scream) or absent altogether (Scream VI).
