Corrected entry: Once the characters have all arrived at the cabin in the woods, there is a scene during a game of "Truth or Dare" where they all enter the basement. During that scene, Jesse Williams' character "Holden" magically acquires glasses that he was not wearing at any point prior. From that point on, throughout the remainder of the movie, his glasses disappear and re-appear multiple times. Most notably, in the scene where three of them attempt to flee through the stone tunnel in the RV.

The Cabin in the Woods (2012)
1 corrected entry
Directed by: Drew Goddard
Starring: Chris Hemsworth, Anna Hutchison, Kristen Connolly, Fran Kranz

Continuity mistake: Before Dana and Marty enter the control room and release all the monsters into the control centre, there is a thermos flask and a torch sitting next to each other on the control room's desk. But once they enter the control room, the position of the thermos flask and torch have changed without anyone touching them.

Trivia: The movie pays tribute to many famous horror movie monsters. The creature with the Buzz-Saws in its head with the Puzzle Orb is based off PinHead. Once it's free, you can see a Chatterbox-influenced cenobyte standing next to it. The people with ceramic masks who tie up and torture the scientists are based off The Strangers. The psychotic clown with the knife can either be seen as a tribute to PennyWise or Killer Clowns from Other Space. The massive killer bat is obviously from the movie BATS. A chainsaw can be heard as the different monitors are showing the slaughter - indicating LeatherFace. The ghoul-doctors operating on a victim while staring into the camera is based off House on Haunted Hill. The Red-Neck zombies brought to life through an incantation from a book is a tribute from The Evil Dead. The Scare-Crow-like zombies who kill the black security guard are based off of the movie ScareCrow.
Question: Is there a reason, that a facility full of monsters would ever, under any circumstances have a System Purge button? Is it just to make satire of the fact that the antagonist is usually stupid?
Answer: As you said, it is a satire of the common Deus Ex Machina trope you find in such films.

Correction: Just because someone wears glasses that doesn't mean that they need to wear them all the time. He may only need them for reading, and he has plenty of opportunities throughout the film to take them off and put them on.
