Yep.
A) Don't think it was north Korea, as plenty have said. I should note here, US old media has dutifully reported, over and over (until they got bored with the story) the "party line" that "officials" say it was North Korea, and trotted out an expert (without naming who they worked for) to say it was North Korea (with no reasoning as to why.) They never even suggested the possibility of someone else doing it as literally all other news coverage on the planet has. US "new" media (i.e. sites that are not just a newpaper or news channel's online portal) did cover it properly. Luckily I have time to listen to BBC News during my lengthy commute, so even if I hadn't read it on The Register, I heard the Kaspersky employee's doubts (having analyzed attacks of South Korean systems and found this did not follow the usual "modus operandi"), and later on the paper trail suggesting ex-employees being responsible.
B) I think I liked the movie slightly more than the reviewer. But, yeah, it was pretty low-brow compared to what it could be. If Kim had been involved with these hacks, I would think it would have to be strictly due to (spoiler?) him being incinerated during the movie; the movie is too far off reality to be a serious (or even much of a non-serious) critique of North Korea or it's regime.
