Loved it at age 11; still find it great at 56.
19 May 1999 | by (Huntsville, AL, USA) – See all my reviews

When it came out, I thought this was the most fantastic movie I'd ever seen. It was easy to identify with the lead character and to share his fascination with the technology that the aliens used to capture his attention and recruit his talents. I particularly remember being entranced by the special effects; the use of vivid color was outstanding among sci-fi offerings of the time. 45 years later, it's still my favorite of the era. I enjoy watching the movie on video and recalling the thrill of seeing it on the big screen for the first time.
