"没用" 这个词的意思是没有价值或没有用处。它来源于汉语，可以翻译为 "useless" 或 "pointless"。

例句：

这部电影完全没用，没有任何新意。(This movie is completely useless, with no new ideas.)

我看了整整一个小时，这个视频都没用。(I watched for an hour and this video was completely pointless.)

如果你要用英语表达这个意思，你可以说 "useless" 或 "pointless"。例如：

This movie is completely useless.

I watched for an hour and this video was completely pointless.
