What was the Point in Guru Unlocking Gohan and Krillin's Powers?

Gohan and Krillin’s powers were unlocked for what? The Ginyu Force still kicked their asses; they couldn’t even beat Guldo! It would’ve made more sense if Goku saved them only from Captain Ginyu with Gohan,Krillin and Vegeta beating the rest.

What was the point indeed

the first time it was worth jack shit- he couldn’t even beat Guldo with the help of Krillin-I still don’t understand what the point in all of that was- it was a waste of the poor animators' time and a waste of 5-10 minutes.

because DBZ is the biggest waste of time ever!
