[Hateandhatred]

I would have rather seen Vegeta assist Gohan in a father-like manner, encouraging him like Goku did, telling him not to fail, not only for him or the Earthlings, but so he doesn't not disappoint Kakarot, that father love and stuff is even more powerful than the Saiyan pride and that he understood that from losing Trunks just now and they'd defeat Cell together ending with some Vegeta reflecting over Goku's true intentions etc.

A bit of what he did with goku vs kid Buu (holding Buu back while Goku prepared the Spirit Bomb), what he did with Gohan (fire at Cell to give Gohan an opening during father-son kamehameha), and what Goku did with Gohan during the Father-Son Kamehameha. It would have kicked ass that way.

Gohan and Vegeta fighting Cell hand in hand, recognizing him as a true saiyan and acknowledging the value of the Earth saiyans etc.

And make the Buu saga not exist anymore.
