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.
YMMV: Scary Movie
Cargo Ship: Doofy and the Vacuum Cleaner in the first one, and Ray and the Clown Doll in the second.
Contested Sequel: Different fans can easily find any given movie the worst or the best. Generally speaking, the biggest fan divide is between those who prefer the Wayans films (the first two) and those who prefer the Zuckers (the latter two). And then there's the fifth movie...
A girl living with her drug-dealing father? Not funny. Having them talk about how cutting crack with baking powder will have people growing muffins out of their noses? Funny.
In the third movie, the President and his bodyguard succumb to paranoia and beat up a roomful of "aliens disguised as humans," a.k.a. handicapped people. And if that wasn't enough, the second line is definitely crossed when the bodyguard opens up an exit...by grabbing a shotgun and blasting through a giant picture of Mother Teresa.
The first film's Scream 2 parody. A woman being stabbed to death in a movie theater? Horrific. A woman being stabbed to death by all the other theater patrons (including Mother Teresa and the Pope) because they got sick of her talking during the movie? Hilarious.
The end of Cindy and Bobby's sex scene in the first film, where Cindy is launched to the ceiling by a geyser of semen.
Hollywood Homely: Very much played for laughs with Cindy Campbell who is played by the obviously attractive Anna Faris yet is constantly criticized over her appearance (this joke is dropped in the Zucker films which portray Cindy as more of a Brainless Beauty type.)
Only The Creator Does It Right: A fair few fans feel this way about the Wayans Brothers, appreciating their cruder, more pop-culture savvy style over the more general spoof style used by David Zucker in the latter films. On the other hand...
My Real Daddy: Fans of 3 and 4 increasingly consider Craig Mazin to be this, as he was the main writer on those two films (and Superhero Movie), which did better among general audiences than 2 did. Tellingly, when he left to do the sequels to The Hangover, the quality of the fifth film dropped like a brick.
Shallow Parody: Increasingly so as the series progressed. The first film took flack for how it was a parody of a franchise that were already parodies.
Shocking Swerve: Parodied at the end of the first movie, where the killer is revealed to be the retarded Doofy, who has already gotten away and is shown taking off his disguise, and is then picked up by his girlfriend and drives off into the sunset. Earlier in the film the girlfriend had no idea that he was even the mastermind, but they're revealed to have been working together in the ending.
Weird Al Effect: $157 million worth of tickets were sold at the US box office to see Scary Movie, compared with $103 million for Scream (1996). But this was only at the time; which has been seen by more more people since release is completely untrackable, and both films retain large fandoms.
