Four more episodes over the Bank Holiday weekend, and I am glad to say that (for me) season 3 is just going from strength to strength!
"North Star":
OK, so I loved this episode, but I am sure it's one of those that a lot of fans don't like. I like this sort of thing - a nice change of pace, something to reassure me that Trek doesn't always take itself so seriously. The western setting, gunslingers vs MACOs, Archer as the Man With No Name (kind of...) - this was all hokey fun. And it had a very nice "Star Trek-esque" message at the end, where the kids were being taught together...good stuff.
"Similitude":
This was a good one, mainly for the acting from Bakula and Billingsley. Archer and Phlox both had some great moments here, as did T'Pol (and obviously Trip). As with much of Enterprise, it takes what you think is a "typical"/well-trodden Trek/sci-fi plot and gives it a fresh twist. "You were a damn fine father"; "And you were a damn fine son". Lump in the throat. Good stuff.
"Carpenter Street":
The premise is a little dubious, but Archer/T'Pol in the past, kicking doors down and leaning on that guy from E.R is kind of appealing for some reason. I don't know if I'd call this a classic by any means, but it was entertaining to watch.
"Chosen Realm":
Enterprise has set a high bar with alien make-up on the whole, so slightly disappointing look for the religious alien race here - but the story itself: Very good. Using Enterprise as a weapon was a good plot device (though similar to that TNG episode where they lost their memories, "Conundrum"), and I thought Archer came off very well in this episode. The alien leader was suitably creepy.
So, an improvement to season 3 for me but as I've said before, even when the story itself is disappointing, I find 'Enterprise' episodes usually have something in to keep me interested.
