The Idiom Jaw Drops

This is also idiomatic, but not idiomatic, because i think often it's literal. Yet, you can only use this to describe things you see with your eyes that are surprising. This idiom ratlyy, for sure. So recently i started watching a new show called halo. I was like, how good could this possibly be? And likis not going to be any good? Oh, my god, since episode one, the quality has been jaw dropping. It's so well done. An, i love it so much. Many scenes make me do double takes because i'm like, how did they do that special effect?"
