My first impressions so far

Gangsta: Best first episode of the season in my opinion
Rokka no Yuusha: only just second in terms of best first episode
Charlotte: Very promising with some good humour to it
Shimone to Iu Gainen ga Sonzai Shinai Taikutsu na Sekai: long ass tittle but is completely ridiculous with its dirty humour
Ushio to Tora: very enjoyable in my eyes and its very much a 90s anime in 2015
