I guess it's the regions, then. I've seen four productions in the last 4 or 5 years.
Even if I weren't excited about seeing another production, I would much rather see Firth in something else - a new dramatic play, an old dramatic play. To me, it's a waste, unless he's planning to come back again in the future.
But, yes, I'll probably see it, as it may be my only chance to see him on stage.
