I really like Star Trek the Next Generation (TNG), Deep Space Nine (DS9), and Voyager (Voy).
I have every episode on DVD.
I went to a Star Trek convention in Las Vegas 2002 and in 2005. Out of the three shows DS9 is my favorite.
My favorite characters from the three are Commander William T. Riker (TNG),
Dr. Julian Bashir (DS9), Miles Edward O’Brian (TNG), (DS9), Lieutenant Tom Paris (Voy) and Commander Chokotay (Voy).
