Review of Proof (2026) on Broadway

If you’re new here, and stumbled upon this blog through the mythical powers of the Internet, welcome! I know a lot of visitors to my website are people who randomly come upon this website through search engines like Google, but I also do have a lot of visitors who come back. Regardless: my name is Ashley, and I started this blog in order to keep track of everything I’m coming across in the world.

I used to live in New York City when I went to college, as I attended the Fashion Institute of Technology for my undergraduate degrees, but when I left the city because of the COVID-19 pandemic and never really returned, I knew that I was regretting my time in college not taking advantage of student deals for Broadway and Off-Broadway productions.

Granted, I had never been exposed to that kind of environment, or theatre at all, so when I started working in New York theatre and spent some time in that world, I jumped back into it. This blog has been a way to document my journey as a theatre lover and watcher, especially considering I don’t like to do short-form video. Written criticism has always been my thing more.

In June 2026 I decided to do a New York City trip over the weekend because I had bought tickets to The Maids. I wanted to do another show, but looked at my options and realized that I had been yearning to see Proof despite the lukewarm reviews. However, what had been stopping me were the high prices.

I ended up buying a partial view ticket for $99 after they didn’t get any Tony Awards. I was Row D (so like five rows back from the stage) in Seat 15, and I honestly didn’t miss a thing. It was worth being up so close because this is an emotional play, so seeing the actors’ faces made a difference here. I’d recommend that seat.

Let’s get into the review! I can see this introduction is getting long.

Now 25, Catherine must confront her father’s death, her own mental health issues, and the existence of a revolutionary proof.

Let’s break down set design before we go into this: this play is a simple outdoor/backyard setting with nothing really changing beyond the characters bringing items to and from the forefront. The passing of time, which are the scene changes, is represented by the outlines of the house lighting up in different colors.

The actual play takes place across a singular week, with some flashback scenes. Catharine and her father, the brilliant mathematician and University of Chicago professor Robert, are talking about her birthday on the patio when he reveals he’s actually dead. We also learn that Catherine is depressed and struggling with her mental health.

Catharine had dropped out of school to take care of her father, who was very mentally ill and probably needed to be institutionalized. Her sister Claire, who is flying in from New York shortly, has been financially backing the family and has a successful career in the city.

Then we meet Harold Dobbs, known as Hal, one of his former graduate students going through all of the 100+ notebooks Robert left behind. Hal is very clearly flirting with Catherine as he talks about how the notebooks hold so much promise, but she brushes him off in a despondent manner. She also calls the police after she realizes he tried to smuggle a notebook out, leading to even more problems when Claire shows up.

As this play dangles between past and present, with a cliffhanger happening at the end of Act I, we start to doubt Catherine’s mental state too, showing how this play pushes on the perception of her and how, like the people in her life, they see her as someone who needs saving. It’s kind of sad, especially considering how she pushes back against this narrative.

Although this can be a very heavy play, the current cast plays off certain moments as very comedic to lay off the tension. We get very little time with Robert (Don Cheadle), and his character honestly doesn’t make a big splash for being the big shadow over the play, but the rest of the cast got quite a few laughs throughout the production.

The stand outs for me though were Kara Young and Jin Ha, which did not surprise me at all. I saw Kara in Purpose and knew she had star power and a commanding presence on the stage, while I’ve heard such good things about Jin Ha overall.

Overall Thoughts

I think this is a good play, but the current production doesn’t elevate the material in a way where I thought this was an excellent production. I mentioned Kara and Jin Ha earlier, but I thought the two main leads, whose names were above the title, were the ones that actually didn’t fully hold their weight.

I’m not sure if it’s because they’ve mainly done theater acting, or if it’s the direction they were given, but I could not get with how Catherine and Robert were portrayed. Ayo is also despondent throughout the course of the play, which makes sense considering the depression, but I thought it actually dragged down the pacing at times and didn’t really show in her favor.

I wanted to like this production more, but it’s too held back in its current form. It’s very restrained. I can’t pinpoint whether it’s the actors or the pacing, but I don’t think this was worth the very high prices they were putting up initially.

Go see it if you can get a good deal, or can afford the higher prices. Support theatre whenever you can.
