I first watched this as a kid, back in 1985, I believe. It struck my as a fascinating and intelligent story, unfolding slowly and perfectly, and Andrew Ellams does a perfect job as the adopted boy Matthew Gore, who one day starts hearing a voice communicating with him. But unlike his little sister make-believe friend Missy, this entity seems to have a separate existence outside of Matthews imagination. It is British, in the sense that it is both well played and quite slow in it's build up. I, for one, enjoy the slowness of it, compared to todays pacing. Don't get me wrong, the series is not at all filled with dead time, but whenever something significant happens to take the story forward, it actually means something. Considering this was more or less a children's show, it is quite complex. My guess is the plan was to make a show that the whole family could watch together. And the fact that season 1 functions so well on several levels seem to support that idea. For any fan of Sci-Fi themes beyond space-westerns with laser guns and spaceships, this is a gem!
I have to briefly mention that there were two more seasons made, season 2 «Chockys Children» and season 3 «Chockys Challenge». Season 2 is far from the quality of season 1, though watchable. Season 3, on the other hand, is dreadful. It clearly shows how much Andrew Ellams carried the first season (he's out of the picture in season 3) and there are just too many things bad about season 3 to even start a rant here.
If you haven't, do watch season 1 of Chocky, it is a true sci-fi- drama classic! Highly recommended.
Fun fact, the opening title music is more or less a rip off of Brian Enos "Sparrowfall". How they got away with that, is beyond me.
