Those things felt rushed, and the whole series to me (yes, it was billed as a mini-series) felt rushed and compacted. It felt like it should have been a full season (just one, but a full one), and that's not unlike what was originally said by Bryan and Michael. So originally it was a full season I believe, but got shortened over the past year to a mini-series. Do note that the change would have happened before the series aired, or even finished production. Otherwise the whole thing would have been impossible to follow.
Do keep in mind that when a show is to be cut off early, they still have to give closure, they can't just stop. So things get changed, plot points move up, etc., etc. This is where a lot of things end up feeling rushed.
