I saw it a few years ago, everyone should give it a try.
You can always follow it up with 1962’s “The Intruder”, another Shatner film, in this one he is a race agitator.
IMDB gives it a 7.8

I’ve actually got that one on DVD. It’s quite good, surprisingly so given it’s a Roger Corman film. I like Corman, but you don’t usually look to him for films with serious social messages. :-) The script/novel was (IIRC) written by Charles Beaumont, a gifted writer who was a big wheel with the Twilight Zone.
