Top 4 in Top 10 best anime by studio Shaft ranked by IMDb.
Studio Shaft's anime trailer, Owarimonogatari
Another installment in the Monogatari series with an IMDb score of 8.2, Owarimonogatari (Mysterious Tales Part 11) takes place significantly later than the other anime on this list. Koyomi Araragi returns, this time having to help new transfer student, Ougi Oshino with a strange problem she has. Specifically, there exists a class that appears in a space where it should not be.
Like many of Shaft's other anime in the series, Owarimonogatari focuses on dialogue, character development and exploration. Owarimonogatari is truly complex and requires viewers to be careful and attentive; so it's no surprise that it's considered one of Shaft's best works.
