According to Broadway.com:
The MCC revival of Carrie will shutter off-Broadway on April 8. The reimagined production, directed by Stafford Arima and starring Tony nominee Marin Mazzie and Molly Ranson, was initially extended through April 22. The production officially opened on March 1 at the Lucille Lortel Theatre, and will have played 34 previews and 46 regular performances at the time of closing.
At least they sold out their inital run and had a few extra days. I'd call that a success, even with mixed reviews. Again, Jen and I enjoyed it very much.
