I had almost the exact opposite reaction. There's something really affecting about seeing an old hero getting back into it, especially given the type of self realization that this story will inevitably entail.
I used to agree that the second two movies didn't need to happen after how masterful the first was, but then I think about my original reaction walking out of that first movie and it wasn't entirely positive. On first viewing I was definitely thinking more about how it lifted themes from movies like The Terminator, but on subsequent viewings came to really love the stuff that OG Matrix did. So, while those other two films aren't my favorites, I don't hold any particular ire for them any more.
This trailer hits enough nostalgia beats from the first film (I'm not sure that isn't the same rooftop tbh) and the question of "Why is this happening again?" seems intended carry the old fans through the whole thing, while audiences who are too young to have seen the original might be intrigued enough to go back and visit it. Keanu is probably a big enough draw on his own to get new folks in the seats after his resurgence in the last half decade or so.
