Well. This was incredible. I hate biopics, so I guess my hype was a little lower for this than previous Nolan films. But this is by far the most compelling "biopic" I've ever seen. It might not be my favorite of his films for rewatchability due to subject matter, but I would say it is his best film. Cillian was great throughout of course, as was the whole ensemble (save for one brief cameo that kinda stuck out like sore thumb), but Emily Blunt and RDJ were the standouts for me.
One notable complaint: The sound issue with the dialogue/music mixing is still a thing. Not as bad as it was with Tenet, but it's still there. I definitely missed some dialogue in parts due to it. That said, see in IMAX if at all possible. The imagery filling that whole screen - including simple close-ups - are totally worth it. As is Ludwig's score, and most of the sound mixing/editing is incredibly powerful.
