This was an adequate conclusion to the "ori" plot line.
That said, the "ori" plot line was a dire extension of the sg1 franchise, with the departure of major cast members and the addition of "farscape" cast in a story arc majorly departed from the previous series driving arcs there was little chance of success. I admire that MGM decided to axe the series and return to the original amazing plot for the final "continuum" movie coming later this year.
If you enjoyed s10 then you will enjoy this. Personally I only watched it all the way through out of respect for the previous series of this truly amazing show.
Series 10 of sg1 was seriously lacking in comparison to atlantis which will hopefully carry on the stargate name for many more years to come.
