Having just watched series one and two back to back and then this reunion special, I can't help but feel that it lacks the same spark. It's still worth the 8.3 but that's more to do with the actors (who do a fine job) and the sense of watching an actual reunion than with the sparkling wit of the script.
Part of what was lacking were some references to the other characters. People like Kira and Francesca deserved a mention but didn't get one. I also thought that some of the character development was unlikely and the ending of Miles' storyline seemed to come out of nowhere.
Too bad, the original series were groundbreaking television and almost instant classics. This reunion special was fun, but no more.moreless
