Just got to the 3rd season of Enterprise. I'm enjoying the shift in tone a lot. It seems like this is when the show really becomes something unique. It's darker and less optimistic now, whereas the first 2 seasons seemed like a total rip of the basic Trek formula... although it feels closer in tone to Battlestar Gallatica now. I was pleasantly surprised by the shift despite that, mainly because I haven't been spoiling anything for myself this time around. Archer is becoming a lot more interesting, simply because he's willingly to kill some guys to get shit done and seems much more aware of his role as captain of the Enterpise. He's no longer doing stupid things, like getting involved in situations that he shouldn't be, and he actually seems to be following his own version of the "prime directive" now, despite the fact that there is still no prime directive in place. T'pol's development is... uh, ok I guess. I predicted her shift from Vulcan behavior to a more human-like character as early as season 1, so it wasn't very surprising. Every character is getting a lot more development this season as well, which is always a good thing.
