Anni- You're killing me again! <g>
I didn't start watching Sg1 for a certain character; I started watching because I liked the movie and all the pseudo-Egyptian stuff. I had to forget about James Spader before I accepted MS in the role.
That DJ ended up being my favorite character? Unexpected but also not hard to *see* (with Jack a close second, btw).
As for the show, I am not saying it's bad; it's good entertainment. It's still very, very well produced, acted, directed, SFX (I'll never forget "The Light" FX), etc., but having been there from the beginning as a loyal viewer, I can, in my experience, say it is a different show than it was then, and the departure of the Shanks will change it further.
It is inevitable and unavoidable. Geez, I'm becoming a living cliche myself now.
