There are a few moments that are slightly under Gohan going SSJ2. Such as Gogeta, Gohan turning SSJ2 against Bojack, Broly reaching his legendary form, Future Gohan dying, Ultimate Gohan, Trunks killing Freezer, and a few others I forget.
Gohan SSJ2 had the advantage of having a properly drawn scene, a good song (and background music, too, along with the Ozaru's cry) and an insane build up.
I don't think Dragon Ball Super will be able to reach that but seeing how they're using Future Trunks again and they kept this touch from the "History of Trunks", you can at least expect to feel comfy watching it, at least for a while.
Meanwhile, Super Saiyan Blue using Kaioken was decent but nothing special.
The fight was even worse in the anime than in the manga for some reason.
I've moved all my hopes of "epic" Dragon Ball action to Xenoverse. These games at least allow you to dream and act on it.
I wish they'd bring back Broly and/or Gogeta. At least Broly, it'd be nice if they explored his transformation further. Especially if it's the next one they'll reach, kind of.

Anyone ever notice that Whis/Vados never bow to Zemu? Everyone else does though.
They bow down to him during the tournament.
