Blogger-type "reviews of the previews" keep showing up in the daily alerts:
So it’s probably anti-climactic to say I loved the show. I liked the way he had Philo Farnsworth and David Sarnoff, the two main characters, narrate each other’s story. I liked how the scenes flowed seamlessly across time and space, from New York to San Francisco, with not much more than two tables and two chairs for scenery. And I really, really liked Hank Azaria and Jimmi Simpson. Damn good acting all around, but Simpson in particular was unbelievably amazing.
Elsewhere, we learn that even though it has yet to open, “Invention” is one of the bright spots in the Broadway box office totals:
The Farnsworth Invention is making a good showing as well, up 13 percent over the last week. figures at the box office dropped 11 percent, the largest of any theatre on Broadway.
Generally, response to the play has been favorable. One would have to say the prospects for its actual official opening look pretty good.
