Just rewatched it on Laserdisc last month (era-appropriate and all) :)

The computer effects are amazing (especially considering it was made in 1983), the concept is very interesting, the acting is a bit odd, and... Natalie Wood sadly died during production (her sister stepped in to help complete the movie).

Her death was even more mysterious https://people.com/natalie-wood-death-legacy-what-to-know-86...
