Disgruntled with my supervisor - be truthful about this in my semi-annual PhD report? I am just done with 2 years of my Ph.D. study. I have some issues with my supervisor. He is repressive, forces his vision on me, e,g, he wants publications in one particular area (and loads of them) to bolster his reputation. He is rude and arrogant and behaves bossy for no reason. 

More importantly, I believe that I have not learned the skills which I wanted to during my study. I spend all my time writing mediocre papers and learning very little. I want to mention that in my six-monthly report.

Now the question is that I cannot change my supervisor, I do not care to either. Fighting with him is not my goal. He is incapable of teaching me the skills I want to learn and I have to learn by myself, which I will do. But I wonder if I must say what I feel in my report truthfully and boldly. If I do that, it will annoy my supervisor and there is a good chance he might even decide to not support me in future if I need something.  

Advice/suggestions?
First and most important suggestion: Seriously consider changing supervisors, and if you can't, give serious thought to finding another university/institute at which to do your Ph.D., contacting relevant researchers and if you find someone who's willing to advise you, making the switch.

But about your actual question:


  A little sincerity is a dangerous thing, and a great deal of it is absolutely fatal.

Only be honest and forthcoming in your report if you want to have an out-and-out fight with your advisor. You might want to do that for various reasons, but assuming you aren't, don't write what you've told us.

Instead, bury it into nuance and insinuation. i.e. without denigrating what you've actually written and where you've published, put it in the context of the hope of writing something deeper or more meaningful, or publishing someplace more central. Also, mention things you would have liked to have done these past 6 months, and explain how the efforts gone towards preparing publications have not allowed you to invest as much time as you would have liked in the other pursuits. That sounds super-polite and respectful while giving off enough hints.
