I haven't watched the movie yet but i don't really see how Superman can win against Goku if he went all in. If Superman let Goku alone for just a few seconds he could do what he did to Cell during the Cell games where he loaded a Kamehameha and used instant transmission to fire it point blank. And i don't think Superman is that much faster then Cell was. Also if i remember correctly in some fights (i think in Goku vs Vegita during Majin Buu saga), blocked punches create shockwaves so big they destroy mountains. And it's also a question of how far into Dragonball we should count Goku's power. During Majin Buu saga he used SS3 and during DBGT he used SS4.
I will watch the video later when i get some time and see if I've learned something new since i'm not to familiar with Superman's full strength from the comics.
