I saw tonight's preview. I was encouraged to see it after reading several reviews about the play being a thoughtful exploration of male friendship. I was also aware of a few critics' grumblings that some issues raised during the play (especially those around race) were left unresolved. After seeing the show, I can say that both viewpoints are valid. Though, my takeaway was that what could be interpreted as the show's "weaknesses" are mostly indicative of shortcomings in the expression of male friendship in the U.S. these days -- particularly the lack of emotional intimacy. In other words, I felt the portrayal of the two characters was pretty darn accurate.
The structure of the play is interesting, with four scenes spread across 13 years. The play hints at the time setting using both LeBron James' career and cell phones (in humorous fashion) as framing devices. There are pretty cool set changes made in the dark, including a set rotation at the beginning of Act 2.
Both performances were tender and honest, though I felt Chris Perfetti was the stronger, more consistent actor. The pair also showed good chemistry, which I expected, given that they've played these roles before in both Chicago and LA. The show also had quite a bit of humor, which the actors played well.
As someone who knows almost nothing about basketball, I can assure you that if you read the full intro section of LeBron James' Wikipedia page, which highlights his career and how much he means to Cleveland, you'll be able to follow along just fine. Sure, you might miss some of the NBA references, but none are critical to the plot.
MTC lists the runtime as 1 hr 45 minutes, though tonight's performance ran about 2 hours 5 minutes, including the 15 minute intermission.
