There is no way to improve your listening without practice while just listening cannot always help to improve your listening score.
I have several tips which may help you.
1-) try to find more advanced listening samples.,
listening to Hollywood series are not always helpful to improve your English skills due to the fact that they want everyone to understand easily.
try to find some movies which use complex grammar and high-end vocabulary. Maybe, watching documentary is useful.
2-)Try to understand all the words while listening.
Be careful every single word and prepare to write down everything.
3-)Do not forget deliberate practice is generally more beneficial.
