Best Star Trek Show

I agree...TOS is a classic and will always have an indelible mark on the history of television but I really think that the Star Trek universe was more effectively fleshed out with TNG, in terms of utilizing the many different races and their viewpoints to create complex and interesting storytelling. I never thought a show that had a Klingon in Starfleet could be realistic but TNG pulls it off nicely and I love how in the beginning Worf was barely a little more than a glorified extra but then in later seasons his life and story are really explored. It created a nice character arc for him.
I also think that Picard's humanity and ethics are so symbolic of the best qualities in people, especially influential and productive ones.
And Data. Very likable and has that childlike innocence and wonder that is so captivating to watch. Long live TNG! Best of them all!
