I loved the first 2 Stargate productions (SG-1 and SG atlantis) -- I've got the entire DVD set of both Stargate SG-1 and Stargate Atlantis (shame it ended after series 5) but after episode 5 of SGU I'm not sure I like it yet.
It seems to me that it's been a bit dumbed down -- I shudder also every time I see the main scientific doctor (Dr Nicholas Rush) - every Scotsman on the planet must cringe at the way he is playing his arrogant role -- I've been in Scotland many times and most are certainly NOT like that.
Dr Mackay in Stargate Atlantis was arrogant but in quite an OK way and at least you got a smattering of Science as well.
I'm beginning to get the feeling that SGU is nothing more than "Eastenders" or "Coronation St" in space. (If you haven't seen UK TV these are just two long running depressing Soap operas in which nearly everybody comes from a dysfunctional family, is mired in debt, has lover problems and in general is a totally depressing statement on modern life - if I had to live like that I probably would have ended it all years ago
My guess is that it wont last past series 3 unless they beef up the story line a lot and go a bit more up market for genuine SCI FI fans.
