在台灣限制級就真的 "未满18岁之人不得观赏" ??

其實這些片子在美國全部都是相當台灣的輔導級.
"R级（RESTRICTED Under 17 requires accompanying parent or adult guardian）：限制级，17岁以下必须由父母或者监护陪伴才能观看。该级别的影片包含成人内容，里面有较多的性爱、暴力、吸毒等场面和脏话；"

Knocked Up (2007) --- R for sexual content, drug use and language.
The Brave One (2007) --- R for strong violence, language and some sexuality.
Lord of War (2005) --- R for strong violence, drug use, language, sexuality.
The Departed (2006) --- R for strong brutal violence, pervasive language, some strong sexual content and drug material.
