What happened to the animation quality in the anime Gangsta.? Everything was so detailed and "perfect" to the last detail in the first couple of episodes, but it substantially seemed to drop its quality. Any reason for it?
As said @ton.yeung said and as stated in this article, the studio producing Gangsta, Manglobe Studio, went bankrupt :
According to animeanime.biz , Manglobe Studio began procedures for bankruptcy on Sept. 29th after months of insolvency. The news of Manglobe Studio’s bankruptcy proceedings wasn’t common knowledge.
Therefore the quality dropped.
For the same reason (obviously), you should not expect a second season or another content related to Gansta, but there can still be a chance that another studio produces it if the Intellectual Proprety of Gangsta get sold.
