(Obligatory nitpick that they indeed never died out and we did grow up alongside them. And even back then, most dinosaurs weren’t giants. But I’m not sure that a movie featuring only, say, dinos smaller than an elephant, or a tiger, would work. People want to see the charismatic gigafauna.)
Alfred Hitchcock's The Birds is technically a dinosaur film.
Zombies are so it’s easier to make it “feel” like a fair fight.
Dinosaurs are big so it’s either a tanks and machine guns bloodfest or humans being torn apart.
IMO a really good dinosaur movie would start with the premise that they never died out, so we grew up alongside them.
