The word in red is a slang expression for ‘movie’. It refers to how light from old movie projectors causes a room to change rapidly from light to dark, with shadows moving on the walls, like the way a room is lit when a candle ‘flickers’. A person can go see a flick, catch a flick, but is not typical to say ‘I am going to the flicks’.
這是一部好的電影
“flick”是電影得厘語用法. 意指老舊電影的放映師快速的切換燈光明滅，牆壁上的影子.
