6. Ezra Miller's Terrific Dual Performance
If you're able to put your opinions about Ezra Miller as a person aside, they absolutely give a remarkable dual performance as both the Prime Barry Allen and his younger, alt-timeline self.
If Miller's twitchy performance as Barry rubbed some the wrong way in both versions of Justice League, here he feels a little more at home, dialling down the self-conscious quirkiness but still remaining a fundamentally, hilariously neurotic character.
And crucially, Miller makes both versions of Barry feel distinct enough - the younger version proving to be a far more impetuous and, shocker, immature iteration of The Flash.
While not all of the emotional beats work fully, Miller nevertheless nails the conflict of Barry's overall predicament - his desire to prevent his mother's death all while risking the fate of the multiverse due to the disruption his efforts cause.
In pure context of their performance here, it's a shame Miller likely won't be back to play the role in the DCU, though it's also completely understandable considering everything.
