If the sets and costumes are first rate, then this production is already a leg up on the last Channing revival, at least by the time I saw it at the Lunt-Fontanne, where the sets were flimsy and looked down-sized in the way that many shows look when they've been touring too long. I actually feared for Channing coming down the stairs into Harmonia Gardens. The costumes looked as if they'd been pulled out of storage from the 1960's and not given much thought other than, hopefully, some dry-cleaning.
I know that I am in the minority in not caring for that revival, even though I appreciated the opportunity to see Channing on stage. I didn't think any of it was up-to-snuff, including Channing, whose performance I found to be fairly mechanical. She also had a tendency to go completely blank on stage when not speaking, as if she was resting while waiting for her next cue. That whole production seemed to exist for the "see her one last time before she dies" mentality and it didn't seem to me that anyone ever considered whether Channing was still up to it at that point.
