I tried Baccano! (Never forget the exclamation mark!!!) because it was said to be mature stuff with action and some real plot that gets you thrilled and thinking or else!
The only thing I was thinking is that it sucks really bad! The protagonists and/or antagonists are all idiots and do not have any likeable nature.
SPOILER: They are immortals trying to make some cool stuff but are all losing cuz it's just not cool!
The story telling is mixed; So you have to deal with episodes occuring at different times. Maybe it`s thought to be clever or just confusing; doesn't matter! For me quite all of the episodes were just boring acts happening at different times and places or universes or whatever. I was so cross after finishing this anime to waste my precious spare time on a crap like that!
Trying to send an epic message to the world but horribly failing! That would be my overall description.
The whole series itself (for me) was an obstacle I had to master to get out stronger (=nerves like steel that I sat it through!) Probably the makers want to mirror real life (without the immortal stuff). Then I have to say they really succeeded! It´s a piece of sh*t without any meaning in the whole stream of time! (But I wanted to get entertained! So: FAIL!)
I rather have another finance meeting at work than watching that show again!
One positive thing: The intro song has quite a rhythm!
