These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Characters: The people in Demons 2 in the car who get into an accident and are promptly taken away by an ambulance have NOTHING to do with the movie.
Ensemble Darkhorse: Tony the pimp is universally regarded as the best thing about the movie.
The same actor portrayed Hank in the sequel which was an Expy of Tony. Needless to say, he too was well-received.
Nausea Fuel: The first person to turn into a demon grows a gigantic boil on her face, which then pops.
Nightmare Retardant: Depends on whether or not you really consider the film to be horror in the first place. It's really more of an action film with horror trappings.
Sequelitis: Part 3 is considered Non-Canon.
Shout-Out: To Gremlins. The creature that comes out of the child demon resembles Stripe.
Too Cool to Live: Tony. He's very Genre Savvy, is the first to take charge of the group when all hell breaks loose, and is Badass enough to fight off one of the demons with a switchblade. So naturally, he gets killed halfway through the movie.
