The first thing about Madoka that caught my eye was the unusual visual style, it is essentially a collage of childish character designs and dynamic backgrounds that incorporates both 2 and 3-D elements that reflects the ambiance and moods of the characters. It combines the juvenile and creepy, and does it well.
This story is definitely a little disturbing, especially if you are expecting something aimed towards younger audiences. At times I felt like the entire concept of Madoka was to deconstruct and obliterate the genre. Overall, I thoroughly enjoyed the series, with particular emphasis on the epic fight/action scenes.
