I read the new news on the crossovers with SGA to come. Then I got to the comments section ... specifically this one. This kind of comment honestly bothers me.
I thought that the O'Neill character was SPOT ON to the O'Neill we all know. He is now a general, and a higher general than we were left with at the end of SG1 and into SGA. MacGyver (sorry for the reference) has played and still plays the character perfectly; and, by what I've read of RDA's general personality, it really translates to Jack. How can anyone say that he ruined the character of Jack in SGU (IMHO).
Sam is now a completely different rank and has her own command ... and it just 'happens' to be command of the U.S.S. Hammond. If Carter doesn't make the decisions that Gen. Hammond used to make in response to adversity, even in dire straights, then she would not be worthy of commanding the vessel. Amanda would have to, even in the short time she has been on SGU, relay a much stronger (less emotional) mindset than she did in SG1. Just because she is a generally strong yet susceptible character in a PREVIOUS series of the franchise, does not mean that her cameos (or even pursuant roles) in the new series have to replay those character faults or even strengths, honestly.
Then we come to the Dr. Jackson appearances. I do believe that his cameos in episodes are very beneath the Daniel we all grew to love, BUT he is not a main character in this series ... NOR should he be. I personally love Shanks' contributions to SG1 but I don't think it would translate very well to the characters in SGU. In general he would definitely conflict with Rush's character in that Jackson is not a true scientist in the sense of the word, yet Rush is an experienced scientist/mathematician. If they were both together then there would be a conflict that the series could ill afford, especially a crossover with someone who is no longer a major player (though I would love Shanks there as a real-time contribution).
Okay enough ranting about it ... please tell me your ideas on the matter.
