The Bakemonogatari series prides itself on a few things: Interesting characters, well written dialogue and a gorgeous, minimalistic art style, all of which shine through in this first part of the series.
Koyomi Araragi is a typical high school kid who's unfortunate run in with a vampire was just the start of his recent streak of supernatural encounters. Over the course of the series he meets a variety of different girls, each with their own other-worldly problems that need solutions, and Koyomi takes it on himself to help them all out. The show is set up in an episodic nature, whereby each girl's arc spans several episodes which typically follows a formula of encounter-problem-solution. While this may seem repetitive, how each arc unfolds is always different and has enough twists, turns and witty conversations to keep each girl's story fresh.
The art and animation deserve special mention, as they're simply incredible and absolutely deserving of the blu-ray treatment. The crisp lines and beautiful colours are done justice here and I'd highly recommend the blu-ray release over the dvd counterpart.
There really aren't too many faults with the series so far, but there are a few. The vast majority of the show involves characters talking, which often leads to minimal animation at times, and the bullet-speed of these conversations may sometimes have rewinding now and again just to keep up in some of the more exposition heavy scenes.
However, this is still a quality show with great characters (especially Senjougahara), exceptional dialogue and a beautifully polished look. More than most, Bakemonogatari: Part 1 deserves your attention!
