Is it worthwhile actually telling the truth on a performance review?

For our performance reviews, we both rate and get rated by our supervisors. So I can give a 1-5 on communication, etc. for a supervisor plus there is space for written comments.

My supervisor has yet to respond to an email faster than in 2 weeks. He hears my input only to totally disregard and force me to do his idea without regard for my opinion and what will actually work in my job. (And there are many other issues, but not worth hashing out for my question)

So question is: I feel like I would give him a 1-2 on a lot of things for this evaluation coming up. And while there are anti-retaliation laws, is it worth it to actually write out what I mean?

My company has a culture (recently) of not meeting as a whole or as individual departments, not asking our opinions- just enacting things suddenly, blindsiding us. So I have no faith in the organization as a whole to make changes, either.

Should I just be generic, lie and just say he’s fine when he really sucks and keep applying to other jobs? It seems like any truth could bite me in the ass.

Note: I have documentation and dates and descriptions of all of the things he and the company have done thus far.
