Now that I've watched the second movie of the series as well, I'm going to review it for you. For your information, this movie contains the ending to the original manga, so it is not mandatory to watch past this one. Even though, if you enjoyed this series, I recommend you to watch the other movies or the anime, or read the manga. First of all, I read the original manga, and there were sadly a few differences, notably the fact that an arc of the manga is missing. The story still works and it doesn't completely feel like something is missing, unless of course you've read the manga or watched the anime. Apart from this and the usual cosmetic differences found in the first movie as well, we can say that this movie was exceptionally done. It strangely looks like all the actors improved their acting during this movie, as they all seem more believable. Especially Light/Raito becomes particularly better in this one. Despite the increased length compared to the first movie, it still remains particularly easy to follow the events, and so many things happen that you'll never be bored once. Definitely worth the time! I watched this with my dad, who had never watched or read this, and he enjoyed it as well. Long story short, watch this and you won't regret it.
