There is lots of stuff that makes you think of deja vu, like the cat from the first one, yet everything is different sensory wise. No predominance of green everywhere (which was a Matrix 2 thing more than a Matrix 1 thing.)

We see Thomas (aka Mr. Anderson / Neo) look like John Wick and it is not clear what is happening besides Jefferson Airplane's "White Rabbit" is playing on the speakers and we are see Thomas go to a psychiatrist and is handed a pill yadda, yadda, yadda.

Also some kung fu and gun stuff but we do not get a sense of what things are happening for we are seeing all those fighting at kinetic impact scenes but not the pre kinetic where the punch hits or the post kinetic and thus you are energized but you get so little plot detail in this teaser trailer. An experience designed to not communicate lore or mythos just sensory information to get you excited, using Deja Vu to carry you forward over 150 seconds.

That is enough info and if I rewatch it I can provide more for there are some plot stuff, but if you only watch it once you will only get about 2 paragraphs of info, even if different people will have different 2 paragraphs.
