I sometimes find that the show has a kid's level of understanding about some things. Like that scene in Buckingham Palace in the second episode, where some security guard in the previous episode throws shade at the Brits for having such a lavish palace for their royal family.
"It's not about rooms. It's about power. That building has one purpose: to say that I'm the Queen, and you are my subjects. The queen might look like a nice old lady, but she comes from a long line of tyrants, who all thought they were better than the rest of us."
No, that building's purpose is to showcase the power and the glory of both the crown and the nation. To show Britain's commoners that they have something to be proud of. That they're capable of creating great artistic monuments that can compete with the likes of Saint Peter's Basilica in Rome, the Palace of Versailles in France, or the Forbidden City in China. It's not about the British monarchy just being drama queens and lording over the peons-it's about national pride and glory.
The same goes for the whole "Viltrumite Empire" reveal that Nolan springs on Mark at the end of the season. Nolan doesn't even ask what will happen to the humans once Viltrum takes over. I mean, sure, if the humans are going to be used as organic batteries, get slaughtered down to a few, or be worked to death as slaves in mines, then yes, fighting them to your last breath is the only option. But what if that's not what they will do? When Nolan took over some bug species after he left Earth, he just rules over them as a king, preparing to get them to join the Empire by choice. He doesn't bully them or enslave them to do shit for him, he just rules them as an aloof overlord. They only did that whole "purge the weak" thing to themselves, then when Nolan took over the bug-people, he just rules them as an overlord, he doesn't cull their weak or something:

What if Viltrum took over Earth, and the only things that change are oaths and taxes? What if, in exchange for allegiance, the Viltrumites continue to let the humans live their lives in peace and even give them some Viltrumite technology to improve their lives? Nolan already promised Mark that the Viltrumites would give the humans medical technology centuries ahead of their time, aside from ending war and hunger.
Heck, at least Transformers 3 told us what the Decepticon Empire would be doing with their human slaves: they're going to put them to work rebuilding Cybertron.
I just wish the show went into depth as to what the Viltrumites would do to the humans once they submitted to Viltrum's rule. Have Allen tell Mark what happened to his race and why they revolted against Viltrum rule, to the point where the Viltrumites destroyed their planet. Maybe the Viltrumites were such oppressive rulers that Allen's people HAD to rebel even though the odds were against them. Because from what Nolan told Mark, it seems that the Earth would benefit from Viltrum's rule, and be spared the utter holocaust of what would happen if the Viltrum Empire were to invade it by force instead.
For all we know, THIS could be Viltrum's endgame for humanity once they take over:
