As best i understand they were "just" online threats, but came in the wake of similar threats to Sony employees and their families.
At this point in time i think there is a subset of internet trolls that get their "lulz" from finding some high profile controversial topic and throwing random threats at whoever is involved.

Now if that is the same as the original hacker(s), never mind if they are actually attached to NK in any way, is another issue entirely.
- The media mentioned that this hack might be NK because of TheInterview.
- A spokesperson from NK replied "Wait and see" http://www.bbc.com/news/world-asia-30283573
- Another email from #GOP came out saying not to show TheInterview
- NK starts denying involvement.
- Yet another email comes out citing 9/11 and everyone gets scared.
4.5, SONY pulls the movie entirely after 4 or 5 major theaters decide to pull it.... after SONY let them out of their contractual agreement and said, in effect, "You do what you feel is right"

The Senate report on CIA torture is what you're missing.
Lets the timeline right
1. North Korea makes its disapproval of The Interview public and complains to the UN in the summer of this year
2. Sony is hacked and passwords are leaked. The passwords are the focus of the story
3. A couple of days go by, no mention of North Korea or The Interview
3.5 I've gotta be missing something here
4. Theaters (not Sony directly) decide the pull The Interview because of threats from NK
5. FBI blames NK for sony hack
6. Obama gets involved (?????)
The sequence of events just makes no sense. Then there are sites like reddit that are completely consumed by the story. The number of posts about it is insane, and there is little skepticism about the bizarre sequence of events or the blaming of NK.
