That was possibly one of the worse series finales I've ever watched. I love SG as much as everyone on here but as it has been pointed out has the person who wrote the screenplay actually watched SG before?
It was painful and shameful to see the Asgard commit mass suicide within the first 5 mins. It's like the writer said "you're all dead" ... Thor "why"... Writer "it was the Salmon moose" I mean come on. To add insult to injury the next scene Ori ships are being taken out with Asgard upgraded weapons on the Oddessy. Hang on, were there not a couple of Asgard ships in Camelot that got wiped out with the first wave of Ori Ships. And when did Asgard use beam weapons!
The fact is the Asgard were to powerful for the Ori so mass suicide was the only way to clear the way for more story lines. The Asgard dying was to be expected but this was not respectful or truthful to the SG universe.
I could go on but most reviews here have mentioned the other flaws through out this episode. I have yet to see Ark of Truth and by all accounts it sounds like this should have been the finale so hopefully my faith will be restored.
