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.
The movie adaptation of The Mask has the following tropes:
Adaptation Displacement: All adaptions since have at least used some inspiration from this film, despite the comics being very different.
Alternative Character Interpretation: Lt. Kellaway while an officer of the law, was he really the tough and no-nonsense authority figure that deep down inside had a sort of warmth to him like he was meant to be, or just something of an overall Jerk Ass who used his position of authority rudely and condescendingly. Sure he may have been on the right track when hunting down the one who robbed the bank doing his job, but considering his overall antagonizing, slightly condescending, mildly and openly rudely insulting attitude (particularly the one he displayed toward Stanley), some (or few) may not have found him to be all that sympathetic.
Designated Villain: Lt. Kellaway is a Jerk Ass cop that ends up being humiliated at every turn and is chewed out by the mayor at the end. We're supposed to laugh but in reality, the guy was trying to arrest a bank robber. He's a Hero Antagonist: In the comics, where he tries to stop the users of the mask from causing destruction and death at any cost.
It should be noted that while he's technically an officer of the law, the film version of Kellaway is still overly antagonistic and surprisingly incompetent. A good example would be when Dorian's men literally throw Stanley at him and he doesn't question the suspicious circumstances behind this at all.
Designated Hero: Likewise, the movie is sometimes called a "superhero comedy". While Stanley is a nice guy and the Mask does briefly joke about becoming a superhero, he doesn't really fight crime except at the end but he's more or less forced into that position since it involves Tina and his stolen mask.
Technically it would be more accurate to say that Stanley grows into the role of the hero while the Stanley/Mask character is far less heroic unless Stanley manages actively direct it/him.
Ear Worm: "They call me Cuban Pete, I'm the king of the Rumba beat."
The Problem with Licensed Games: There was a tie-in game released for the home consoles. The problem? As with any super hero that has infinite powers and is nearly invulnerable, the character has to be seriously stripped of powers and made weak to make the game work. As a result, The Mask is often beaten up by low-level thugs with pocket knives. And as you'd expect, the level layouts, bosses and plot progression really don't match the film in anything but the loosest sense. Otherwise, it's a mostly fun action platformer.
What an Idiot: Tina getting captured by Dorian's men wouldn't seem so bad if it didn't occur right outside the freaking police station! Why she didn't just turn around and head back in is anyone's guess.
The Saturday morning cartoon version of The Mask has the following tropes:
Best Known for the Fanservice: Literally in "Flight as a Feather," with the one-time appearance of the Mayor's ex-girlfriend Cookie BaBoom (who is a strip — er, exotic dancer). You know there's a plot about a Swedish karaoke contest and the Mask losing his feather and running through the city to get it, but once you see that entire sequence with Cookie, you'll forget about that right quick.
Bizarro Episode: "Flight as a Feather" was a weird, envelope-pushing episode (and that's saying something, given the rest of the lot). It didn't have Stanley in it at all, The Mask actually has an excuse to cause trouble (Mrs. Peenman barking at him to keep quiet and everything he did to try and retrieve his feather), there was no villain out to destroy the city (like Pretorious) — unless you count Cookie trying to assassinate the Mayor, and the Cookie BaBoom sequence felt more at home on a show that carried a TV-PG rating (which is why FOX Family and CBS never aired this episode).
Canon Defilement - A rather odd official example- Lionel was completely ignored for the film and cartoon. Instead, they gave the role of Lt. Kellaway's partner to Doyle, a character so completely different it's not even safe to say he's based on Lionel.
"Funny Aneurysm" Moment: Everything about Cookie BaBoom's assassination plot in "Flight as a Feather" stops being funny due to 9/11, the Janet Jackson Wardrobe Malfunction fiasco in 2004 (well Cookie's Shameful Strip is still a little funny even after that), the Bill Clinton - Monica Lewinsky scandal (though the idea of a corrupt city politician having an affair with a woman who has a job in the sex entertainment biz is more reminiscent of Eliot Spitzer, which wouldn't happen until the late 2000s). and an incident in which a man named Brian Wells robbed a bank with a bomb strapped to his neck (not as outrageous as a suicide belt bikini, but the principle's the same) and died when it detonated. To put it in simple terms: There's no way in Hell a sequence like that would even be considered suitable to air on anything that's not PG-rated (at least in America), as America has gotten more squeamish over content on TV between the 1990s and the 21st century (especially if it's sexual and/or is considered "in bad taste" due to a recent tragedy).
The beginning of "Counterfeit Mask" where the Banana Republic Liberation Army freedom fighters hijack a plane. The whole thing turns out to be a dream, thankfully, which is more than what anyone can say about 9/11.
And after that dream sequence we get a scene where a Jerkass security guard doesn't bother to look at Stanley's luggage (which was switched with one containing counterfeit money. Imagine if it was a bomb...) because "a wimp like you couldn't sneak a peanut past a sleeping baby". And when Stanley insists he gets his bags checked he gets thrown out. These days, with airport security tight as ever, this would be hideously illegal and would cost a TSA agent his job.
Hilarious in Hindsight: The episode "Broadway Malady" centers on a disastrous musical made from the "Mad Monkey" movie series, much like the Spiderman musical would years later.
The beginning of the episode, "Future Mask," has The Mask playing on a mini-golf course. The prop on the seventh hole can easily be mistaken these days as a character on the [adult swim] cartoon, Squidbillies.
Suspiciously Similar Song: The first season opening theme owes its melody and style to "Hey Pachuco" from the movie adaptation. Two other openings (one used in American syndication and the other used for season three and international airings of season two) don't sound like "Hey Pachuco" at all.
What Do You Mean, It's for Kids?: Well, what do you think? It's a 1990s cartoon based on a PG-13 Jim Carrey movie (not unusual in itself, many PG-13 and much higher rated movies inexplicably got Saturday morning cartoon series at that time. Anyone remember the cartoon adaptations for Robocop, Beetlejuice, The Toxic Avenger, and Rambo?) which was also adapted from a dark, very violent comic book (again, not unusual, see above). It ran with a decent amount of Parental Bonus and other elements which might be questionable.
