Saw it last night.
It's a triumph, and the Captain America Trilogy is easily the best superhero trilogy we've gotten.
The movie is touching, hilariously funny, heart-wrenching, and full of the best superhero action we've seen yet. Every character is handled with care, they're all given character defining moments, and no one feels superfluous or shoehorned in. The Russos showed in this film that they're the guys for the job when it comes to Infinity War.
Cap remains the best superhero on film, RDJ brings his best MCU performance to date, Tom Holland is head and shoulders above the other two cinematic Spider-Men, and Black Panther is a complete badass.
This movie has it all.
