After just watching the first episode, I will break it down by parts...
Cast: I feel the cast is really uncoordinated and probably the worst part of the whole SGU "expedition". The kid genius seems to be nothing more than the comedic sidekick for the main guy Rush. He hasn't really added anything useful but the occasional laugh. I don't think the "main" people really mesh well and will drag the show down unfortunately. Everyone seemed to be standing around with their thumbs up their butt not knowing what to do and that's my next point.
Story: (thus far) Seems interesting with some somewhat new twists to the SG series, but with all the new gadgets and the learning curve they are going through on Destiny it feels like a "been there done that" from Atlantis. At two different parts I won't go into for those that haven't seen it yet, I felt like some of the actors/actresses were going for academy awards and were failing miserably. It felt like watching daytime drama TV with soap operas. Three of the actors were just plain terrible. Christopher McDonald is probably one of the worst actors there is and I honestly can't look at him with a remotely serious face as a Senator after seeing him in Happy Gilmore. Jamil Walker Smith reminds me too much of a poorly acted Lt. Aiden Ford. They could have found a doorknob that is more menacing and chaotic than this guy. Last but not least, Elyse Levesque is a terrible actress thus far and in my opinion the only thing she's worth on the show is that she's gorgeous. They definitely need some of that because this cast is horrible.
CG and Camera: (thus far) is about the only good thing about SGU so far. They seem to have updated the graphics and technology they are using to film these shows because I was really impressed with how it all looked. The music is utter garbage, but you can't win them all.
As far as this show goes so far, I rank it a 6/10 for the first episode which is the most important next to the first season finale in my book. I truly hope they improve and get this show moving come episode 2 and on.
