The way I feel about the last two episodes, and the tone that it delivers, is that despite the bad times (and basic apocolypse) that they're living in, they are still able to settle down and have a laugh on occasion, it feels more like real life. The colony is in a position that they can let some people try to lead a normal life. Granted, this is being said from someone who knows the backstory and what happened/is about to happen later in the main story. There might be a fair bit of fan servicing, but being a fan from since season 3 aired it's been like a nostalgic hit to me, and it's great hearing the voices of the original series actors again.

Again admittedly this comes from the perspective of a long time fan, but so far I've really enjoyed it this series, and look forward to seeing what happens.
