I've found the two trials I was on to be interesting to, but that in no way makes me want to be on jury duty.
OP: the best way to get out of jury duty is to not try to get out of jury duty because everyone at the court knows what you're trying to do. The best way to get excused is to somehow identify with the defendant and make it fairly obvious you share experience with him, her, them.
For example: last month I got called in and spent two days going through the jury duty selection process. Being a middle aged white dude means I'm like jury gold if you're a prosecutor, but, in this case, I didn't really have to try to get out of it because i was the only person in the pool that owned multiple commercial properties and one of the defendants was the landlord of the other. After the section process was done, I was like the first guy the prosecutor preempted. You just have to be able to tie your own experiences with these of the defendant that would make it likely that you would empathize with them on a personal level.
