It’s easy to slip into resting Grinch face, considering the beating of an election we just went through and the onslaught of exhortations to switch into holiday mode. It might feel like a tough transition, but there’s still joy to be uncovered out there — and the Dallas Theater Center’s production of “A Christmas Carol” just might help you locate it. Their musical adaptation of the timeless Dickens tale speaks to the potential for rebirth and redemption in all of us, a message we could probably all use right about now, and it includes more than a few surprises in the reimagined classic. And luckily, it’ll be a happy constant at the Dee and Charles Wyly Theatre, 2400 Flora St., for the next month. Turn that Grinchy grimace upside down starting with a pay-what-you-can performance at 7:30 p.m. on Wednesday, November 23. The show runs Tuesdays through Sundays until Wednesday, December 28, with tickets for those performances ranging from $20 to $104 at attpac.org.
