"Which Trek series can you not stand" - does not compute! DOES NOT COMPUTE! 
I wouldn't say I particularly dislike any of the crews, but I did find myself going off Janeway in the later seasons of Voyager with her ever-changing morals and mood swings between episodes
I also found Seven a bit too "shouty" and in-your-face, and Chakotay and Kim suffered from woeful underuse, so I find it hard to get emotionally invovled with the characters during the last two or so seasons.
To start off with, though, I thought they made up a very interesting crew, second only to DS9. Inconsistencies in the writing of stories and characters did a lot to hurt my enjoyment of the show, not the cast/crew.
