After ten years of the show, fans of Stargate SG-1 were left with the ultimately disappointing episode `Unending' to finish the 10th season on. If people didn't know that this movie was being made to tie up the plot lines from the Ori story arc then there would've been outrage.
So, with a lot of story threads to draw together we are given `The Ark Of Truth' to conclude the adventure.
The story basically centres around the location of an Alteran artefact that may be the key to stopping the armies of the Ori. Daniel, possessed by the spirit of Merlin, managed to send a weapon back to the Ori home galaxy designed to destroy ascended beings in season ten, but the armies of the Ori are still there, carrying out the crusade in the name of their gods.
With Adria ascending in `Dominion' we also have the problem of an Ori who has managed to reach the same level of existence as the Ancients.
So, with the army now on it's way to Earth, SG-1 - led by Cam Mitchell, has to take the Odyssey through the hyper-gate back to the Ori galaxy and find the Ark as it is the only weapon capable of stopping the Priors in their tracks.
The plot itself is typically formulaic SG-1 stuff with no real surprises for fans of the show. There are some delightful nods to technology that we see in later seasons of the show, the prototype DHD and the original idea for the stargates are done rather tongue-in-cheek but good nonetheless.
The banter between the members of SG-1 is up to it's usual standard, a great speech for Teal'c when he talks about killing in the name of false gods and the scene with Cam and Sam at the end did make me smile.
There is the typical cardboard cut-out `man from the IOA', played by Tim Guinee, who hampers the efforts of SG-1 and the return of an old adversary is an attempt at a `b' story to liven up the action sequences. Unfortunately, the return of this adversary does not have either the power or the menace that it had in previous episodes and one must assume that all people working for the IOA are either completely incompetent or just plain stupid.
Julian Sands returns as the Dosi, leader of the Priors, but his role is criminally underused and the chance for some genuine suspense and fear are given away in favour of Adria. This is a shame as Sands does so well when playing the villain.
The main story, the search for the Ark, is good but too much like `The Quest' from season ten and the whole thing feels much like a two part episode cut into a movie rather than a movie in its own right. This should've been made for the end of the series rather than `Unending' and then you could have left it there. It might have been better to have done a mini-series like Sci-Fi did for the end of Farscape, which would've given the writers more time to flesh out the ideas and not make the ending feel so rushed.
All in all, fans of SG-1 will be pleased to see the conclusion of the Ori story line but it will leave you wanting more in the future. With `Continuum' coming out later in the year you won't have to wait long. Chevron 7 locked!
