Dunkirk
It's pretty good, but boy oh boy do I hope Nolan goes back to sci-fi now. Like, I understand that this was a childhood dream and stuff, but now you've done it, so like... you're good, right? (Please?)
Yes: Fionn Whitehead manages to magic some dimension and depth into Tommy in spite of the script, the cinematography of the air combat scenes is so gorgeous I want to get each and every shot printed and framed to cherish forever. Just in general, lots of Nolan-worthy jaw-dropping "holy shit" moments.
No: The attempt to address shell-shock/PTSD through Cillian Murphy's "Shivering Soldier" is as weak as a forced apology from a six-year-old (especially disappointing considering Murphy has demonstrated himself more than capable of pulling off such a character in other performances) and—I cannot stress this enough—whoever was in charge of the color grading deserves to be drawn and quartered. There are shot/reverse-shot situations where both the ocean (and the sky!) magically change color. Not to mention that the film is so attached to maintaining that orange-and-teal color palette that there are scenes where poor Kenneth Branagh looks like he went to the same tanning salon as Prez Trump.
Meh: Hans Zimmer takes the "time, yes the theme of EVERY CHRISTOPHER NOLAN FILM is TIME, yes THE SCORE OF THE FILM IS BASED ON A ~CLOCK~, GEDDIT??? TICK-TICK-TICK-TICK" thing a little far at times (though other times it's just the perfect amount of hammy) and the editing is flawless... until the literal end of the film, where the "Wham! How's that for an ending, huh?" shot comes about three or four incredibly "meh" shots before the movie actually finishes—all the more disappointing considering how one of Nolan's great strengths as a filmmaker is how consistently good he (usually) is at ending with a bang.
