There are plenty of plays with only two characters. I've even seen a few in which one actor plays multiple roles. I've also seen plays with time-shifting aspects, and devices akin to dream-sequences. But, combining all of those elements into one play can certainly cause confusion. Such is the case with "Mary's Wedding."
There are definitely things that merit praise.: The two leads manage a truly remarkable juggling act, the projections are frequently beautiful and evocative. But, I can't remember ever being quite so lost.
The plot is a nice, serviceable love story amid war, which is all the more reason to wonder why playwright Stephen Massicotte chose to complicate the narrative so needlessly. Despite the significant difficulties I had, I don't wish to steer you completely away. Perhaps if you are prepared for its eccentricities, you won't be thrown quite so off-balance.
