I'm going to tell my friend that his sci-fi manuscript that he's been working on for almost 4 years is a bad beat for beat rip off of star wars.
Why would you be so critical of your friend's work?
Since I've read his manuscript I have to give an honest review about it, It's a massive rip off of star wars.
Your friend has been working on this manuscript for a long time, it would be hurtful of you to insult their efforts. If you don't like it don't comment on it at all.
He needs to know there are issues with it.
If you really want to critique him you should be kind and honest. It can be hurtful to accuse someone of something like that and say it meanly.
