Looking back to 1988 when I first saw TNG I always thought it would never last. It was trying too hard to be Star Trek with it's even further in the future setting and similar plots and sets plus some of the cast weren't that good compared to the originals. I saw them on rental video tape because the BBC wouldn't pay out my money to buy the show at that time. When it went to a second season I was taken aback somewhat, mainly because the new shows weren't available at my local shop!!!
