修改原因
修改前Don't lose your time on this series: it gets boring after the first season.
修改后Don't waste your time on this series: it gets boring after the first season.
Don't lose your time 不适合表达这里的意思。Lose time 常用于延误造成时间损失：We lost an hour because of the traffic。一个人把时间花在没有意义的事情上，应使用 waste。
Spend time 是中性表达，只说明时间花在哪里。Waste time 则包含判断：这段时间花得没有意义。对比 I spent an hour on the report 和 I wasted an hour on the report，后者暗示这一小时大概没有带来成果。
动手练习

waste — 这里说读这些评论没有意义，常用表达是 a waste of time。A loss of time 在其他语境可以表示时间损失，但不是这里评价事情不值得的自然搭配。
说出一项你觉得浪费时间的活动。解释原因，并说明你现在改做什么。
Scrolling through news apps before bed is a waste of time for me because I forget everything I read by the morning, so now I read a paper book instead.
