Citation :: Lowered Monster Difficulty

A form of Villain Decay. The longer a monster is seen on screen, the easier it gets to defeat or avoid. Maybe mowing down the cannon fodder tired it out or something. If a writer is good, they'll have some damage occur to it from previous battles, or deliberately point out that the monster is toying with the main characters more due to personal grudge. Otherwise, it's clearly the plot giving the main characters a break.

This is especially obvious when the heroes don't have any powers or anything technically to distinguish them from any of the other humans that were easily killed.

Aspects of Lowered Monster Difficulty include:
•You can see it coming. Early in the movie or show, the monster hides in the shadows, and kills its prey without even being seen. It can also be anywhere it wants to be as long as nobody was looking at it. Now it can be detected from a distance, and moves a lot slower. The heroine can outrun it long enough for an escape plan.
•It takes its time to kill the main characters. Non-important characters like police officers are killed in seconds. For the main characters, it just stands there and roars, or makes threats or evil jokes, and even when it attacks, it tends to miss a lot. The villainous equivalent to Kill Him Already.
•Attacks that previously did absolutely nothing start actually affecting it. Gunshots start knocking it back, and punches and kicks may cause it to recoil.
•Newfound respect for Mook Chivalry. If the menace is a pack of creatures whose teamwork was what let them prevail over the victims, they may suddenly decide to engage the main characters one by one and get taken apart piecemeal.

If the monster becomes less difficult when there are many of them, that's Conservation of Ninjutsu - of course, contrast with the fourth clause above. Related: Strong As They Need To Be, where the heroes' powers fluctuate as the plot demands.

In video games, this may downgrade bosses into regular encounters. If the monster's difficulty decreases over a long series, it may be because the characters are getting stronger and the monster can't catch up. In role-playing games, however, this is to be expected because in most cases, your party gets stronger while the enemy monsters don't.

Citation :: •The Ubervamps in season 7 of Buffy the Vampire Slayer. Took Buffy SEVERAL EPISODES to kill ONE of them... and in the finale, each of the newbie slayers takes down dozens.

◦And even that one Ubervamp had lowered difficulty, going from stake-deflecting skin to being decapitated with wire. (Buffy's hands presumably got an upgrade to avoid having her fingers cut off in the attempt.)

◦Not only Slayers, but normal humans Giles and Wood (badass normals), Dawn (sort of a badass normal), Xander (sort of a badass normal just due to years of experience), and Andrew and Anya (just normals, not badass at all) are able to dispatch some of them, sometimes without even hitting anywhere near the heart.

◦Writer/creator Joss Whedon even mentioned this in the episode's commentary, handwaving the problem by saying that that "isn't what it's about."

◦Normal vampires had similarly varying levels of capability. It would seem more likely the "ubervamps" weren't really any better than the earthly variety, just uglier. The first one was probably handpicked by the first so it was very hard — like the vampire Big Bads in the early seasons — while the rest were just common Mooks.
