Why "the Karate Kid" and "8 Mile" are the same movie

Two masterpieces of the American cinema, one storyline. Our top-notch staff here at "the daily emmett" have been working tirelessly to harmonize the stories into a user-friendly guide that parallels these epic adventures step-by-step:

THE HERO:
8-Mile: B-Rabbit (played by Marshall Mathers)
the Karate Kid: Daniel-san (played by Ralph Macchio)

THE MENTOR:
8-Mile: Future (played by Mekhi Phifer)
the Karate Kid: Mr. Miyagi (played by Pat Morita)

THE ARCH-RIVAL:
8-Mile: Papa Doc
the Karate Kid: Johnny Lawrence

THE GANG OF BAD GUYS:
8-Mile: the Free World
the Karate Kid: the Cobra Kai

INITIAL DEFEAT ESTABLISHES UNDERDOG STATUS OF HERO:
8-Mile: B-Rabbit begins the story by being served a lyrical beating by Papa Doc, the leader of the Free World at his first free-style competition. The only white kid in the inner city rap battles, he just doesn't fit in.
the Karate Kid: After moving to Reno from Jersey, Daniel gets sand kicked in his face when he unwittingly offends Johnny and his friends from the Cobra Kai at a beach party.

THE PLOT-DRIVING NARROW ESCAPE:
8-Mile: Rabbit and friends face near-disaster during an unfortunate meeting on the street with rival rappers "the Free World", during which a gun is pulled. B-Rabbit is later beaten without mercy.
the Karate Kid: Dressed as a shower stall, Daniel-san is nearly killed by a group of skeletons known as the Cobra Kai.

THE TRANSCENDENT MENTOR:
8-Mile: Mekhi Phifer gives B-Rabbit the magic advice he needs to discover his inner gangsta (this is one of example of an epidemic that is spreading through Hollywood, the phenomenon of the "magic black man", which I will reserve for a later discussion).
the Karate Kid: Through eastern philosophy and chopstick fly-swatters, Mr. Miyagi teaches Daniel how to be the toughest karate-master in school.

CONFLICT WITH LOVE INTEREST INCREASES TENSION:
8-Mile: B-Rabbit's girl Alex is caught with Wink, a shifty character full of empty promises. A gangsta beating ensues.
the Karate Kid: Daniel-san's girl Ali is caught with Johnny (leading to one of the greatest moments in movie history, Daniel with a plate of spaghetti in his crotch and the initiation of the popular "run-out-of-the-room-while-people-laugh-at-you" sequence).

TENSION WITH MENTOR SETS UP FINAL CONFRONTATION WITH RIVAL... OR IS IT WITH SELF???:
8-Mile: A conflict arises between B-Rabbit and Future, which must be resolved before the final show-down may take place.
the Karate Kid: A discouraged Daniel-san lashes out at Mr. Miyagi. Resolution comes in a moment that will make you re-examine your life, as Miyagi shows Daniel-san that he has in fact mastered Karate by waxing-on and waxing-off.

HERO FIGHTS HIS WAY THROUGH THE GANG:
8-Mile: B-Rabbit must rhyme his way through the entire rival rap gang, "the Free World" to win the chance to take on Papa Doc himself.
the Karate Kid: Daniel-san must fight his way through the entire Cobra-Kai in order to take on Johnny, his arch-nemesis.

THE FINAL BLOW: WEAKNESS IS STRENGTH
8-Mile: After being seemingly decimated by the previous rap which attacked B-Rabbit's most vulnerable areas (e.g.- his mom's a hoe, his girlfriend's a hoe, etc.) B-Rabbit brilliantly uses the momentum of that blow to gain street-cred and expose how comparatively non-gangsta Papa Doc really is.
the Karate Kid: After what seemed to be a career-ending blow to the knee, Daniel uses his injury to set-up the infamous crane kick. This results in the only face-blow in the tournament that lands without penalty.
