This was a terrible episode and a terrible build up to the whole Vegeta is after his vengeance against Frieza from universe 6 Frost.
Previous episode was building up Frost Vegeta battle so much and the beginning of this episode looked like we get to see the old school bad ass Vegeta go all out on this Frost, but all we get is one punch and everything is over. Remember Vegeta was the villain that killed kids before and killed Nappa because he was stupid, and now he not only spares but doesn't even "Punish" Frost. The writers, and i know Akira Toriyama too has started to re-write and forget the original material. This is evident in the many changes he has given to Dragon Ball super, from making Gohan a weakling to making the rest of the Frieza army stronger then his Ginyu force, to the ultimate one turning the 2 wishes that the eternal dragon grants on Earth into 3 for no reason what so ever.
But the conclusion of this episode was really stupid too! Why didn't Vegeta just do what Goku did in previous episode and just throw the robot on the ground?
This show has been going down hill from the beginning and i only hope that the conclusion is much better.
