Too bad, really, with the recent changes to the writing team and the bringing in of Manny Coto to oversee the stories and production. Unfortunately what we're seeing now on the show should have taken place in season one. I feel like the show has been rebooted this season, and the first season of post TOS Trek is always a little slow to get off the ground.
It's a shame the current team won't get a chance to get up to speed and make Star Trek: Enterprise a true prequel to TOS, instead of the disconnected, Voyager-like story to a far off part of space with the Xindi arc.
Can't really say I blame UPN... although I'll bet Sci Fi network could make it work. :-)
