I just saw the first three eps of this, and I must say, I'm very impressed so far.
Firstly, a VJ from my local music station, MuchMusic is a main character! How cool is that? lol
Secondly, Robert Patrick as a Colonel. Awsome, even though it was just a cameo.
Also, the CGI is beautiful. The way they portrayed Atlantis is a work of art.
Jack O'Neil, Daniel Jackson were also guest stars on the first episode, and the new cast is very likable, and the make-up is great.
I'll stop my praises for now, what did everyone else think of it so far?
