'This was special. This was rare':'This Is Us' offers a graceful goodbye in series finale

The cast's reunion, sans Chrissy Metz (Kate Pearson) and Justin Hartley (Kevin Pearson), comes a little over two years since the "This Is Us" series finale aired May 24, 2022.

"I wanted the finale to capture a moment in time of an American family, and also this American family," the show's creator Dan Fogelman told USA TODAY in an interview at the time. "I knew that Rebecca would pass in the penultimate episode and the finale would be this slice-of-life day, and with it the message that, ostensibly, just because someone dies, they don’t leave the painting."
