I am now enjoying watching American TV series.
Not only can I have some fun but I can also learn English.
But I am confused whether I should open subtitles or not?
If I use subtitles, I can easily understand content of the dramas.
But if I didn't, I can also practice listening.
Should I use subtitles?

Go for it - no need to worry about distraction.

I think you should turn off the subtitle try to know the meaning without scriptIn the reality you won’t see the subtitle while you chatting

let the subtitle on, have a glance while you need it
