A useful picture: something so far above the normal size that it makes people react. Not just big — big enough that heads turn, that you notice it before anyone points it out. The word carries the feeling of standing in front of something whose scale is beyond the ordinary.
Two branches
量級大到令人側目
這一支就是核心畫面本身：講規模、強度、速度或數量遠高於平常。
to a huge degree · adjective · B2
Very big, very strong, very fast, or very powerful — far above the usual level, so that people really notice it. Used about amounts, sounds, effort, speed, and how much something changes or helps.
巨大的；極大的
好到令人讚嘆
從核心的「超出常規」轉一個方向：原本量到讓人驚呼，這裡是好到讓人驚呼。中文說「這場表演大得驚人」不通，但說「好得不得了」就是同一股情緒——說話者被震到，所以用了最大的那個字。
excellently · adjective · C1
Excellent — so good that you want to praise it. Used about a person, their work or ability, a performance, or something you really enjoyed.
極好的；很棒的
