What can they reveal? Nothing!
But it is a solid trailer. With viral content to match.
Great action. A few laughs. Keanu in great shape! A hint that there is a new arc with just enough Neo-nostalgia to sit back and absorb, too. John Wick on sci-fi steroids. Carrie-Anne looks great!
Quibbles? No Fishburne. No Mr Smith. Soft reboots often fail. Novelty is there but might be short lived and burn out within a few scenes?
Anyway: sit back, take a chill pill and embrace the MATRIX..
