Went into this show knowing completely nothing about it. Caught a few scenes off of toonami and decided, 'hey this looks semi interesting'. So glad I did.
What really drew me in to the show was how often it switched from being 'lighthearted', to dark in a few seconds. The character development is another thing that drew me in. I like how even the simplest of characters had a personality or back story. No character bored me.
The show has a total of six arcs, my favorite, easily being the fifth one. Masterpiece. The fourth and sixth one however seemed a little weak to me. I couldn't, for the life of me get into Greed Island without skipping at least a few parts. I just wasn't interested in the antagonist of this arc.
The sixth arc, Chairmen election, was better FOR ME, than the fourth one. I liked the new addition of characters in this one. However this one too, I found a tad weak. In my personal opinion, I think this arc was rushed.
Overall, this is a GREAT and binge worthy show that I highly recommend to anyone.
