The Ron’s review published on Letterboxd :
I'm a little late seeing this film, but I finally got around to it. I didn't love it like some people, but it's very good. The most impressive thing about this film in my opinion is how good it looks technically considering it was released in 1968. If I didn't know the year it was made ahead of time there's no way I'd guess 68 because it doesn't appear dated at all. Overall it's a solid sci-fi experience.
