My favourite of the Star Trek serieses has to be The Next Generation. The Original Series was groundbreaking for its time but I don't think it has aged well and now looks very silly and dated. The more recent series never quite recaptured the spirit and originality of TNG. There were some truly marvellous pieces of TV in that series, such as:
- The outwitting of Moriarty in "Ship in a bottle"
- The entire episode "The Inner Light" (I was so engrossed that I had forgotten I was watching TV by the end)
And, of course, there is the episode "Hide and Q" where Picard (surely one of the greatest characters in all of TV) defeats an immortial, omnipresent, omniscient alien by quoting Shakespeare at him! What could possibly be more awesome than that?
