The Tripods - Series Two
Although I saw the original series broadcast back in the 1980s I don't think I ever this sequel. If you remember the original then you might be interested to see what happens inside the City of Gold. On the other hand maybe your imaginiation has better special effects than this. Unfortunately this is the last of the television series so you never get to find out what happens in the end. Maybe it would be better to go and read the books.
