New this monthOther mistake: During the Sekai Taikai tournament, all of the characters and extras wear new, pristine gis (karate uniforms) that never seem to get dirty. As they use their own gear, you would expect at least some wear and tear from previous use, or some marks from the fights, training, sweating, etc., to show occasionally, but the uniforms all seem brand-new all the time.
Audio problem: When Tori and Kwon are talking in the hotel lobby, Tori says, "Maybe you shouldn't have let him kick your ass," but as she turns her head, her lips aren't moving.
Answer: Just like in the original film, some guys want that brutality. Johnny in part opens the dojo because of his past rivalry with Daniel and to train a kid that's being bullied. But also, other kids that are being bullied want to join in order to learn to fight back. Johnny is also teaching the Cobra Kai creed (Strike First. Strike hard. No Mercy.") so that's why he opens his dojo with that name and the old Cobra Kai dojo's past reputation is exactly what he wants to elicit.
