Not sure if there is another thread on this.
I have seen it and thought it was a much better film than Arc of Truth. It had swearing and seeing Baal cut in half was really quite a step into a darker version of Stargate, along with Daniel's loss of a leg, Apophis's (cant spell his name) head getting cut off. There was a lot of gloom in the first half and that really showed a different side of the characters, and showed that things were not so easy.
I did think Teal'c went over to the good side a little too easy though.
Still, i enjoyed it and it was nice to see both the old characters and the new.
