Do you scrutinise movie sound effects?

That 'metallic' sound when someone pulls out a knife or picks up an axe in a horror movie always seems pretty stupid...tools don't make sounds on their own

Mostly ambient stuff and good sound engineering/editing.

Prometheus is one that has excellent audio engineering, especially in the underground sections, and especially with great speakers.

I also like hearing about the "recipes" behind iconic sounds.

I scrutinize camera angles. I want to see more top down shots like in old school video games.

I scrutinize firearm sounds in movies constantly.

I've seen at least a couple of shark movies where the predator emitted a type of roar underwater while in attack mode, which I thought was really lame, cheesy, unnatural and unnecessary.

Kissing!!

Ugh

I hate the sound of kissing in movies. I don't know if they add sound effects or the actors are directed to kiss loudly, but it's like nails on a chalkboard to me.

I agree with db20db that sharks do not roar and it's really cheesy when they do in a movie.

I think more than the effects, I scrutinize the volume. Like, certain things that wouldn't be loud are too loud, but other things don't even make a sound or go unheard by characters when they shouldn't. Bugs me.

Sometimes, if its too loud, and the dialogue is not as clear... I was going over this a few days ago in a movie. It seemed to use gimmick music if that makes sense.
