This was difficult for me to rate, because while it is an exceptionally well done show, I just don't think it was the show for me. All three actors were phenomenal (and I have seen numerous shows with them), but the story didn't go to where I thought it was heading, and there were some parts where I wasn't sure what was going on.
There were some laughs, but the meat of this story definitely makes you feel a little uneasy and uncomfortable and makes you think, and while that is definitely the entire point, I just didn't feel that it was my cup of tea. Your mileage may vary, and I would still recommend this, just be wary.
Note about the Gateway theatre - the first couple of rows are using the plastic, folding chairs, but the rest of the theatre has much more comfortable seats. If that matters to you, get in line early!
