Taylor Walker’s review published on Letterboxd:
This movie was pretty bad. Everything happened so quickly I did not have enough time to care about anything that was going on in the screen. Everything was just going through the motions and, BAM! movie over. Nothing was explained, you just assume what's going on.
The premise was sort of interesting, but this is definitely not a challenge meant for Goku & co. Maybe for first season Sailor Senshi or Doraemon, but not for post-Turles Z-fighters. They are above this stuff. This is like fighting a group of six Saibaimen a year after perfect Cell was destroyed, and being almost obliterated. There is no point.
Most boring (official) Dragon Ball movie I have ever seen. Skip it.
