Though it is just an advertisement. It's pretty poor, the characters and designs do not use the new character designs, rather it used the old Yamamuro designs. The background was a blank colour with no actual location, just sorta in space (maybe). Shenron (Shenlong) is a horrendous 3D model that feels entirely removed from the rest of the scenes. Goku is pretty dumb, though fitting as an ad in that particular location, but it is a shame either way. Frieza (or Freeza) just sorta makes an appearance and turns golden. Broly, however, does not make any appearance despite it being an ad for the movie ofhis name.
The throwbacks to the original Dragonball, Z, Super and some of the movies were a nice addition. But the only thing directly related to the upcoming movie comes after the credits roll, showing a small trailer for the movie.
Audio is fine enough for what it is. The only particular standout moments are when they use the old opening themes for dragonball and dragonball Z Kai.
