I'm kind of glad we don't see Broli get beat up by ssj3 Goku. Because that would have been terrible. When it took Shenron to beat Broli in movie 10, and a weakness to water to beat his clone in movie 11. Fighting ssj3 Goku and losing legit would bring down his legacy, and losing to plot like every other time would make Broli...on the level of mystic gohan.
SSJ3 Goku was awesome in the movies though. We got to have more fanservice with the form there than in the Buu saga really, and it became irrelevant after that, so I would've liked to see that form against an undead Broly. Even then, I doubt Goku would've just solo'ed Broly even as SSJ3; the plot likely would've required him needing help to do so.
And not for nothing, but Broly's power had increased dramatically from film to film anyway, going from movie 8 to movie 10... If he had another film after the Vs SSJ3 Goku in hell scenario, he would then reach another new height if he was brought back with the Dragon Balls like Frieza...
But ya know, the road not taken since he's non-canon, yadayada.
Sounds like this calls for:
A few things:
-I came in thinking I'd get bored of the episode like I have most of these pre-tournament stories (especially the poacher episode and the one about Tien/Roshi), but I'm legitimately interested in where they're going to take Frieza. So far, they haven't f-cked him up with any indication of "turning over a new leaf" nonsense. He's as evil as ever, but he's also seems to be playing some form of Xanatos Speed Chess. I don't know what he's got going on, but he might be the key to keeping this arc interesting. One thing is for sure: Frieza is this arc's wild card.
-Goku didn't want to kill the assassins, but as Frieza rightfully points out, they were either gonna die there or die via getting their universe erased. Felt like a forced attempt on the writer's part to cause tension between Goku and Frieza (which was unnecessary, since Frieza attacking Goku from behind as he did int he episode is sufficient for tension purposes). It'd be one thing if the assassins were already knocked out (kind of like with Burtur and Recoome on Namek), but they were actively trying to kill not just Goku and Frieza, but Baba as well.
-Don't really buy Frieza getting stronger in Hell just by being strung up in a cocoon, but whatever.
-Good fight scenes!
-What is Buu still doing in the opening song? They fixed the ending song by adding Frieza.
7/10
Also, I'm going to go out on a limb and say the spoilers about Frieza betraying Universe 7 weren't fake and that this WAS Toei's intention as of three weeks ago. Remember how they changed it from Goku fighting Jiren at the exhibition match to him fighting Toppo? These guys don't plan that far ahead. They probably ended up changing their mind and saving Frieza's betrayal for later in the arc.
Also want to point out, mental training has been shown in Dragonball since the beginning. Tien is a master of it and Picollo does it consistently. Hell, Goku and Gohan recently did it in super when him and Goku did a small tournament in their minds with Goku being Krillin. Lol...it also happened in the manga in Super during one of the first episodes when Goku stopped Lawning and conjured up cell and Frieza in a mental battle. Frieza training in hell should not be questioned.
