* AngstWhatAngst: Tanya ends the film telling the heroic cat that "it's just you and me now, Clovis" with a happy smile. Certainly not the reaction one might expect from someone whose parents were slaughtered in front of her not even an hour ago.
** To be fair, it looked less like a smile and more of a ThousandYardStare. If anything, she's most likely just numb from everything she's been through.
* AudienceAlienatingPremise: The fact that Charles and Mary are [[spoiler:in an incestuous relationship]] caused June from Podcast/HowDidThisGetMade to point-blank ''refuse'' to discuss the movie until the other hosts accepted her convoluted work-around.
* SugarWiki/AwesomeMusic:
** "Boadicea" by Music/{{Enya}} plays over the end credits, and it's simultaneously soothing and one of the creepiest parts of the movie.
** At several points the 1950s instrumental song [[TitleDrop Sleepwalk]] by Santo & Johnny plays, specifically [[spoiler: when Tanya is telekinetically forced to dance with Charles' dead body.]]
* EnsembleDarkhorse: Clovis is an ordinary cat whose owner takes him to fight crime and ends up being the most competent and badass character in the film who assembles a cat army to destroy the Sleepwalkers.
* FridgeLogic: Why would demons that are expressively part cat have ''other cats'' as their mortal enemy and [[WeaksauceWeakness one weakness]]? For that matter, why are they called Sleepwalkers? They're shape-shifting demons who eat virgin's souls -- none of that involves sleep!
* HamAndCheese: A point in the movie's favor is that the three leads - Creator/AliceKrige, Creator/MadchenAmick, and Creator/BrianKrause - all know exactly what kind of movie they're making and are having the times of their lives in their roles.
* HilariousInHindsight: ''VideoGame/DwarfFortress'' players will get a kick out of the fact that a catsplosion is what saves the FinalGirl.
* MemeticBadass: Clovis, leader of the cat army.
* NightmareRetardant: The Charles [[InvoluntaryShapeshifting startled shapeshifting when spooked by Clovis while driving]], what would normally be a [[SurrealHorror surreally terrifying scene]] in theory becomes unintentionally comedic, especially when Charles' head inexplicably becomes a toddler head on a young adult body in the midst of the odd colleague of reptilian feline morphing.
* PoorMansSubstitute: It's pretty obvious music composer Nicholas Pike is trying to emulate Music/DannyElfman in his score.
* SignatureScene: The murder by corn.
* SpecialEffectsFailure: The attacking cats always look very much like noticeable puppetry. The morphing effects are also not very convincing.
* {{Squick}}: If the [[spoiler:incest sex scene]] wasn't creeping you out enough to start with, it [[spoiler:pans over to the mirror and shows their monster forms]].
* SoBadItsGood: [[WebVideo/TheNostalgiaCritic Nostalgia Critic]] didn’t call it the funniest Stephen King movie for nothing. The film is packed with insane ideas, hammy acting, and ridiculous kills. It's a shlocky monster movie that ''knows'' it's a schlocky monster movie.
* TheyWastedAPerfectlyGoodPlot: At one point, Charles mentions he and his mother constantly having to flee from men in old cars who wield lights and guns -- most likely because they're constantly on the run from the authorities, as they would need to keep feeding on young girls in every town they move to. Some reviewers have remarked that the Sleepwalkers being hunted would make for a ''much'' more interesting plot.
