以下是修過文法的句子:

Dads don't automatically become Dads the moment they're born. It was my first time being a Dad. So... that's why, my daughter, please cut us some slack.      
爸爸我也不是一生下來就是爸爸，爸爸也是頭一次當爸爸。 所以...女兒稍微體諒一下

In some ways, one's family is the most oblivious. But what's so important about knowing? In the end, what helps you overcome obstacles isn't brains,but someone who'll take your hand and won't let you go. All in all, that's family.    
某些方面來說 或許家人才是最不懂的。但懂不懂有那麼重要嗎？最終消除隔閡的，不是無所不知的腦袋，而是手牽著手，永不放手的那顆心。總的說來  ，那才是家人。

Even for heroes, even if it's an even greater hero,the people they go back to in the end are family. The scars we receive from the outside world, the scars we receive from life experiences... even the scars that we receive from family... Those who'll embrace you and be on your side until the end, afterall, are  family.
別說是英雄，哪怕是最厲害的英雄，最後也會回到家人身邊。
在外面的世界所受的傷害，在生活中留下的傷疤， 甚至是家人留給我們的傷痕 ...那些會擁抱我們、永遠支持我們的，終究是家人。

備註: The scars we receive from the outside world, the scars we receive from life experiences... even the scars that we receive from family...(此句文法不正確，但我想保留原來的語氣，所以不改)
