Just finished The World is Beautiful
There are a few problems with it. Stemming from the mix of deep elements to light heared situations, and its deus ex machina. However, I think that this anime does it well and in a way that makes it acceptable.
There are many times in novels that stuff needs to happen just because. And in that a media series can't really show everything.
Some anime don't do this well, but I think that this is a decent exception.
Anyway, I'm liking it
