it is a crying shame that this series has been cancelled but this was an excellent ending to the show. It was very well scripted, the whole story came together nicely calling upon a whole string of previous story lines and references. I particularly liked the end scene which was a nice nod in the direction of the star trek franchise. This show has been both a great success in terms to sci fi with great story lines and an great sense of humour which is not easy to achieve. I am glad they did not leave it as a cliff hanger for the movie and look forward to the arrival of said movie. I would much rather of had at least 2 more seasons out of these characters.
