Eh, I'd argue it's only silly if it's handled in a silly way. Just like uplifting can be pretty silly depending on the story, but also allow for effective serious storytelling in other contexts
I think it's silly because I'm struggling to think of a way to execute on the idea of "robot dinosaurs taking over the world" that isn't handled in a silly way. And even if they do come to something that's effective on paper the trailers aren't giving me any faith that the dialogue and voice acting will be able to keep it from falling back into the silly zone.
