I thought this movie was pretty good. The only thing I didn't care for was the wrapped-up-with-a-bow conclusion and the cliche scene where everyone "wakes up" and stops fighting and asks "what's going on."
The idea of opening up "thirdspace" seems like it would've created endless possibilities for continuing the series. I guess there was no time before the cancellation. Did anyone else think "Star Trek: The Motion Picture" when Sheridan went on his Spock-like space walk toward and into the artifact? Another similarity was having the artifact "calling" people, kinda like Spock and V'ger. Overall, I was pleasantly suprised by Thirdspace. While I probably would be willing to watch In The Beginning again, I probably won't watch this one a second time.
