There was no buildup.

I don’t hate Sentry as a character, but the way the MCU seems to be introducing him feels completely unearned and honestly should be world-breaking.

My biggest issue is scale vs explanation.

We’re talking about a character whose power level is far beyond Hulk, Thor, or Captain Marvel—something that’s basically stronger than a nuclear weapon. Yet the implication is that this power comes from a human-made serum, similar in spirit to the Super Soldier Serum.

That raises huge questions the MCU doesn’t seem interested in answering:

• How were humans even capable of creating something this powerful?

• If this was possible, why didn’t it immediately become the biggest political and military issue in the world?

• Why wouldn’t this trigger a global arms race that makes nukes obsolete?

At least with Hulk, it worked because there was a more grounded movie that circled into him.

With Sentry, if the serum worked, then the MCU is basically saying humans solved godhood—and nobody cares?

This is why a cosmic or extradimensional origin would make way more sense. Cosmic power externalizes responsibility. A serum that casually surpasses nuclear deterrence completely breaks the internal logic at least of the MCU.

Honestly, Sentry should’ve been a solo movie:

• Show the unethical project and how was they able to make such powerful weapon

• Show the fear and consequences

• Show why this power had to be buried or erased

• Slowly reveal the Void as the cost of human arrogance

If Marvel doesn’t address the political, ethical, and global consequences of creating someone stronger than a nuke, then Sentry doesn’t feel tragic or terrifying—just shallow.
Sentry should have been a Solo Movie
