I just saw a high school production last week, and I still haven't gotten over the impact. A VERY powerful piece, but you have to stage it well or it'll actually feel boring and lose the intensity. It's a great show, though, and you should definitely do it-- and it's an awesome way for actors to show off their versatility, playing characters of different genders, different ages, different beliefs and personalities.
The best thing about the show is that since it's all taken from real interviews, no one's a completely flat character (well, maybe Fred Phelps, but he's in there for a split-second) and it's great to explore all of the nuances. Even Matthew Shepard, who's only mentioned and never apppears in person, isn't depicted as a totally blameless martyr.
