I found The Ferryman totally enthralling when I saw it a few days post-opening last fall, with the original cast. I revisited it last night, and while I still admire the play and production, I thought most of the juice was out of it and the replacements were largely not on the same level as the originators. In some cases (especially Brian D'Arcy James and Holley Fain), it seemed like they had been directed to basically replicate the performance of the person they replaced. The accents were all over the place. Among the new cast, the most successful performances came from Fred Applegate, Sean Delaney and Collin Kelley-Sordelet, to my mind.
I would be interested to hear from others who saw both the original and current casts about how their feelings changed (or didn't).
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
