While, nothing specific stands out that I remember now, I have some rant coming...
Why is that we go to all these worlds, have access to all these super technology, yet the command center is still run by the same computers when the show started. These people never heard of Moore's Law?
And just when you think, the Earth people built the hyperspace plane/ship, it had to be destroyed. Man - such incompetency. May be the shows writers dont have much faith in our human ability....or that if we do get technically advanced during the show, they would not know how to write the story....
And in future...Asguards wont give us anything even if they owe us...that is writers block for you.....one thing for sure...at the end of the show, we will have the same stupid stargate set with same stupid equipment running the same old technology.
