Your first Trek DVDs are DS9 season 5? What happened to 1-4?
Anyway, I've been enjoying the shit out of them. I'm on season 5, disc 3. My schedule doesn't allow for more than one evey couple of days (though with Monday Night football canceled I may have me a little marathon tonight). I don't mind because by the time I was done with season 4, season 5 just came out.
I think 6 comes out in a week or two. Sweet.
