With the help of the latest special effects, William Shatner along with Sam Witwer, who played in Battlestar Galactica and Star Wars animation, play James T. Kirk at different ages. It is about Kirk's journey to the afterlife.
Although it is good, I'm not as blown away by it. The special effects are a novelty. It is a lovely way to say goodbye to Kirk. Kirk seeing his younger self reminds me of 2001, A Space Odyssey.
Lenard Nimoy died almost ten years ago. All our old favorite actors are dying off, which makes this all the more touching.
The final scene looks like it could have been shot in "The Volume" which is a Lucasfilm spherical stage where all the walls are screens to create artificial scenery. The Mandalorian series was created primarily on this stage.
