It’s a difficult thing to critique a piece like Mulu’s Pub and Café, as it was written with an a honorable goal in mind--exploring the immigrant experience in Canada—and is obviously a labour of love for many of the people involved in the production. However, as written by Robin Arthur, editor of Touch Base, a free monthly newspaper focusing on issues of diversity, the play lacks a satisfying dramatic arc. Characters hold discussions in a completely unnatural way and often preach to the audience, rather than interact with the other characters on stage. The actors run a wide range of acting experience and ability, but everyone brings a passion for sharing their stories to the table. The play is successful as a vehicle to stimulate discussion, but less so as an actual piece of theatre. Still, it is exciting to see people working together to explore some difficult but important issues. Runs today (8pm) and Sunday (2pm, 8pm) at Sacred Heart School of Halifax, 5820 Spring Garden, $10-$15, 445-0432.
