Disturbing: Alluring to young children who love cute dogs or are infatuated with royalty and extravagance; reminiscent of how seemingly innocuous people use candy, dogs, and displays of wealth to deceive and prey upon child victims.
Traumatizing: At one point "suicide" is casually dropped as an option for Rex (the lead protagonist) to get away from his problems. Charlie, Rex's best friend, pushes Rex off a bridge into icy water with the clear intent to kill him and take on Rex's role of "Top Dog"
Messages: Exposes children to vulgar obscenity of various types. Promotes horrific values such as arrogance, entitlement and doing whatever it takes to get ahead, even if it is by engaging in immoral/unethical behavior. Promotes sex and violence. Overt allusions to perverse sexuality. Bizarrely portrays a female as a sex fiend that attempts to mate with Rex despite his clear refusal. The female dog uses tape to bind him. She lays on top of Rex as if forcing him to engage in sexualized behavior against his will. Elsewhere, Rex unapologetically seduces a female dog right in front of a large bulldog's girlfriend. Rex exhibits no shame, fear, or concern despite the threatening presence and aggressive behavior of the jealous bulldog. Rex then partakes in "fight club" which resembles an illegal dog fight in a makeshift arena late at night.
Authority figures throughout the movie are portrayed as oblivious bumbling idiots.
A perfect allegory of present day politics: two dogs battle to be recognized as "top dog". Deception, betrayal, attempted murder, fabrication of evidence, and feigned grief/emotion are used to eliminate the rightful 'top dog'.
Final scenes and themes coincidently are reminiscent of the U.S. Capitol Riots. Friends of Rex (Latin for 'King') unite to fight the illegitimate 'top dog' Charlie ('fool' in Britain; 'Communist' in military slang), interfer with the ceremony where he is to be formally named 'top dog', and rescue Rex from a giant Hill of memorabilia that had been set ablaze by Charlie in an attempt to get rid of Rex and everything bearing his resemblance.
This movie is sickening. It targets children and exposes them to depravity and disturbing messages.
