- Acceptable Targets: The film itself is this for many people because of the sloppy effort to turn a mobster movie into a family-friendly animal comedy.
- Audience-Alienating Premise: For many viewers and critics, the rapping kangaroo is made of this. For those who genuinely wanted to see him, his downplayed screentime in favor of a plot about the duo's tangling with the mob was no less offensive.
- Awesome Music: If there is ONE good thing that the sequel, Kangaroo Jack: G'Day USA, gave us, it's Jackie Legs' cover of "I'm Gonna Knock You Out". Considering that he's voiced by Jeff Bennett, this is to be expected.
- Big-Lipped Alligator Moment: The scene with the talking kangaroo came from a hallucination sequence that was shot just for the trailer, once the studio became afraid that they'd have a bomb on their hands.
- Bile Fascination: The Uncanny Valley nature of the titular kangaroo is sure to evoke this for some people; The fact that it was actually a run of the mill gangster comedy hastily edited into a kid-friendly animal comedy is almost certain to do the same for those who want to see just how this panned out in the final product.
- Contested Sequel: A family-friendly Direct-to-Video sequel, Kangaroo Jack: G'Day USA, was released a year after the first film. Here, the kangaroo is turned into an actual character with his own role in the story, satisfying those angered by his wasted role in the original film. However, others detract the sequel for the same reason, thinking that the novelty of watching the titular kangaroo had pretty much worn off by that point.
- Critic-Proof: Though critics hated it and people found the premise ridiculous, the film still grossed $70 million domestically, and it made the top box office office gross of that particular week (which various comedians at the time mocked to no end).
- Designated Hero: Charlie and Louis put clothes on a kangaroo they believe they killed just to amuse themselves, and Charlie flirts with Jessie in a way that's practically sexual harassment, including groping her by the breasts and forcibly kissing her. How are they the sympathetic heroes, again?
- Ensemble Dark Horse: Par for the course for Christopher Walken, who with his usual bizarre delivery manages to completely steal the show for the few minutes that he is onscreen.
- Humor Dissonance: Charlie and Louis find it funny to putt clothes on a kangaroo they believe they killed. Most audiences found this tasteless.
- Idiot Plot: Aside from the main characters' obvious stupidity of losing the money to the kangaroo, there's the fact that Sal makes things unnecessarily complicated to kill Charlie and Louis. Instead of just killing them there in America, he sends them all the way to Australia for a hitman over there to kill them. Even if Charlie and Louis didn't encounter the kangaroo, there are a hundred things that could've gone wrong (like Charlie and Louis catching onto his plan and disappearing with the money, an idea they actually entertain in the movie).
- Just Here for Godzilla: Hundreds of children wanted to see the kangaroo.
- One-Scene Wonder: The eponymous kangaroo himself (in his rapper persona). In the movie proper, he's only present in a hallucination scene.
- So Bad, It's Good: Between the clashing tones of a dark mafia comedy and a goofy kids film with a rapping kangaroo, there's certainly a group of people who find the awkward fusion rife with unintentional hilarity.
- The scene where Charlie slurps an extra hot jawbuster, and then Louis slurps the same jawbuster Charlie put in his mouth.
- The farting camel scene.
- They Wasted a Perfectly Good Character: The titular kangaroo only appears for about five minutes, and only raps as part of a hallucination sequence. The viewers who only came for said kangaroo were sorely disappointed.
- Took the Bad Film Seriously: Neither Michael Shannon nor Marton Csokas act like they were aware there was a talking, rapping kangaroo in the movie.
- Uncanny Valley: Unsurprisingly, the rapping kangaroo falls squarely under this for most viewers.
- What Do You Mean Its Not For Kids: Despite what the trailer and sequel imply, it's not a kiddy comedy with a talking kangaroo. It's pretty adult and leans toward PG-13.
YMMV / Kangaroo Jack
