The good news is that Attack on Titan Part 2: End of the World (Blu-ray release 2016-3-23) is less bad than Part 1. However, being less bad does not mean it is good. At least this time the plot is not driven by stupidity, so it is no longer unwatchable. Unfortunately, the action is significantly less exciting this time. Anyway, we get an explanation of the origin of the titans and a government conspiracy, which almost make sense. It’s still a very bad idea to turn Mikasa from being a very likeable character in anime to very non-likeable here.
Note: there is a post credits scene at the end.
