I tend to agree with you. Slow motion does not feel so novel any more. X-Men ones were cool because of a hint of playfulness. Second time it would not have worked as first. But in Age of Apocalypse they dialed that scenario to eleven. Instead of three people it was saving the entire school from the explosion. All the while keeping the tone of levity and fun.
I say this has not worked so well anywhere else. Not in Age of Ultron. Not in Justice League. But that Wonder Woman one in the beginning of Justice League was fun. Man of Steel was also great imo. Fast movement like that brings a sense of continuous and breathtaking action which they try to capture on the page anyway. Just don't make it such that its difficult to follow the action.
My younger brother was watching Justice League and called it out right at the beginning. Batman is too bulky and moves so slowly. Its awkward to watch. My sister said that too. Thankfully that was the beginning and they enjoyed the film. But the point is if you aren't trying to catch that sense of almost breathless, heart pounding action what are you even trying? Comics get away from that as they are static pictures. And in other places they look cool because it is extraordinary. But in superhero films moving so fast that the world slows down isn't extraordinary. Even Batman dodges bullets.
There has to be a feeling of breathless action. That Warehouse scene in BvS was great. I don't know about TV shows. But for films slow motion shall be used rarely. Its boring to watch without adding something more.
