Dragon Ball Super is by far the weakest Dragon Ball Series in the franchise, and sadly it appears that this movie is following the same standard.

The Red Ribbon army is back with another set of never ever mentioned members that create machines that are capable to pose a threat to the good guys. It makes you wonder how they were never mentioned until this point other than: the author didn't come up with them.

There are other problems that jump from minor but questionable to "If that were possible, why weren't they doing it before?". Bulma still uses the Dragon Balls to make herself look "more beautiful", following the tradition to misuse the Dragon Balls for selfish reasons.
You would expect the Dragon Balls to be kept in a secure place in cases of crisis instead wasting wishes like that for trivial and selfish wishes.
The real problem starts here: Piccolo wishes for his potential to be unlocked.
Why didn't anyone do that until now? You know how much time has wasted watching characters train to get stronger or work for the next power up? Piccolo fused with GOD to get the power to fight Cell. Most of that effort has been in vain since just wishing from the Dragon Balls to do that could have solved several issues in the story.
Not only that, but it adds to the pile of many plot devices that give a free power up that likely nobody else is going to use:

• Super Saiyan God Ritual
• Always carrying the Potara in the cases of crisis. Considering Goku and the gang have a good relationship with the gods, that should not be an issue.

Meanwhile Goku, Vegeta and Broly train so Broly learns to use his power. A pointless scene. Why not just wish from the dragon to be able to control your power and your potential to be unlocked like Piccolo?

Gohan could wish his potential and power never to disappear and he could fully dedicate his time for his family and research.

Speaking of Gohan, the movie is about him. Not only did he neglected his training again and became weak, but also neglected his family because of research. So this movie focuses Gohan to reach his peak again. And because this has been done so often, it makes you wonder if Gohan will keep all that power or has to start from scratch.

Also the visuals look better than in the trailer which looked like the opening from Dragon Ball Z Tenkaichi Budokai. But they aren't visually pleasing like any other Dragon Ball movie thus far. A disappointment considering Dragon Ball Super Broly set a standard for fans what future productions have in store.

Overall, I recommend skipping this movie. The meat of the plot takes a while to get through and it's not something we haven't seen thus far.
