thank you again for the explanation,

just as you said bad cinematography leads to this. but when you create a 200 million+ dollar movie at least i expect great cinematography. look at for example shape of water from Del Toro.

look how beautiful it is shot. very little blur. so again it is possible. but it simply depends on the director.

another example the chariot race of ben hur a movie of 1959 looks better then modern day movies in terms of cinematography.

just look at that link. there is also some light blur in some scenes which is fine, but most shots are sharp. so if it is possible in 1959 you tell me it is not possible in 2023?

also in animation movies mostly all scenes were sharp, like for example in the movie Akira

however these days we get blurry backgrounds now as well in animation movies. for example in the new mario brothers movie.

you can see mario fighting kong. and i am like why? why do you do that? just because you can should not be the reason why.

if a director chose for a close up shot and blurs out the background fully without any detail left. it is done on purpose. take note that i make a difference between light blur and so much blur you can not see anything anymore from the background. and that is what upsets me, because you on purpose destroy the scene while that is not necessary.

it is the same as you have 2 people standing still and the camera is lightly shaken which lagues so many tv series these days. like andor for example.

and very well i understand depth of field, but that all depends on camera work on how much you want depth of field or not. that is what it comes down too. in the end it is a directors choice.

that is why i firmly believe if your a good director you can let every scene breath and let the viewer decide what they want to watch in the scene.
