I did a marathon viewing of the second half of S3 this weekend...finished everything from "Harbinger" to "Zero Hour".
My thoughts have always been the same: S3 is a massive step up from S1 and S2 (duh), but something else popped out at me. This was a remarkable season in the entire franchise...
I was able to watch "The Xindi," the disc one extras and the new docs on disc six last night. Having skipped season 2, the change in tone from the end of S1 to S3 is dramatic. This is almost like two different shows...and that's a good thing. Enterprise needed to do something...
