This is the first Enterprise episode that I have thoroughly enjoyed and stayed immersed because there weren't any serious plot holes, goofs or suspended reality moments that normally jolt me out of the experience.
Of course, it's Star Trek, so we never feel that there's any real danger to our main characters but everything kept moving with plenty of interest as to how things will play out, with lots of humor and good commentary. I always enjoy Commander Shran.
This is what Star Trek should be. A crisis solved by people rather than a technological fix. Space, tech and alien cultures are the playing field that makes it interesting, but the crisis is solved by intellect, not magic tech that's fixed or implemented at the critical moment.
To introduce someone to Star Trek Enterprise, a mini-series of only the Andorian episodes would be good, but need to include one of the episodes where the Vulcans show their displeasure of the listening post and monastery being destroyed.
Actually, this episode did have one of my pet peeves: Would you walk away from your car with the door open? Why do they always leave their shuttle doors open?! :D.
