Notwithstanding its popularity, Bakemonogatari has always been thorough; despite its supernatural tone, it is still a series in which most of the time consists of long talks between characters and the development of these latter, dealing with deep issues such as sinfulness or the need to overcome a murky past. This review is foremost a comparison with the anime, that is to say I am not going to rate the characters and the plot per se, but how good the adaptation is regarding the former material.

The manga goes for the most sheer rendering of Bakemonogatari. As it should be, the dialogue between characters remains as the foremost radix of the story, but adding an special emphasis on underlining the core of the story. To everyone's astonishment, there is not a high amount of text despite the gift of the gab that the characters have in the anime and the novels. Instead, there is an interspersing humor and drama almost perfectly fitted without any type of filler, what makes the plot very forthright and a lofty conspectus of everything that makes this series so great.

There is plenty of metaphores in the artstyle of this manga, to bet decisively on a beautification of each scene with much more subtle and allegories. The characters are given the most attention, thus there are characters depicted on every single panel. The artstyle of Bakemonogatari mainly focuses on the attitude and pose of the characters, making each design unique.
The artstyle is more realistic than in the anime. At first it is a bit of a shock to see detailed character designs and a less conventional style, but it also fits very well with the spirit of the manga, plus the characters apparent a more epicurean aspect, something that has always been present in the Monogatari Series.
Even though the art is not as mindblowing as Berserk, the drawings are precise, detailed and fresh, with their own quirks.

In a nutshell, I loved Bakemonogatari both as an anime and as a manga. However, I recommend people who have not watched the entire series yet to watch the whole thing first so the nods to other seasons will not spoil the story for them.
