Bakemonogatari..............Where to start? It is mainly a supernatural/mystery type of anime. It has some proportions of slight comedy and some romance in it. I haven't read the manga so I am solely basing this off of the anime.
Story
Its a confusing anime to follow but it is intriguing. The story line in my belief is simple but the dialogue or script makes it seem more mind boggling than what appears on the surface.
Art/Sound
The art isn't the best but it manages. The sound doesn't really have anything that stands out.
Characters
The characters in this anime are very interesting and have their own complicated back story to them. All of the characters in this anime are complex in their own way and evolve over the 15 episode anime.
Enjoyment
I personally enjoy this anime because I like the "mind-boggling" type of animes. It kept me on my toes watching the whole thing. It is slow in the beginning but it picks up around the 4 episode.
Overall
If you are the type to try anime regardless of the type then I would recommend this and if you like mystery or "mind-bogglers" than i would highly recommend this for you.
