Mononoke, Mahou Shoujo Madoka★Magica Recommendations
If you see the sypnosis of both animes, they may not look too similar: Mononoke is about a medicine seller in which job is to try to protect people from Mononoke/demons, while Madoka is basically an Evangelion-like turn on magical girls. If you watch both animes, then you'll be surprised that they would look somewhat similar: plot twists, weird imagery, unsettling moods, fighting against monsters, and places taken something from an overly surreal world.
Mononoke is more episodic as it tells a different story through it's arc-driven plot, but if you're looking for dark, psychedelic anime, then those shouldn't be missed.
In a facet of artwork which revolves around an dynamic plot one could argue against these similarities as one is episodic and the other series' based.
However, where art and thriller is concerned both shows are exceedingly similar in psychological aspects.
At first glance radically different: Mononoke is a semi-episodic mystery/horror, divided into miniarcs in a way similar to Monogatari, whereas Madoka Magica is an unorthodox and thrilling take (but with linear plot) on the magical girl genre.
In more than one way, they couldn't be more similar! Both are original screenplays and 12 episode anime that feature heavy psychological elements and psychedelic visuals that set them apart from the norm. Plot twists, surreal horror, deconstructive/harsh takes on human nature and of course, a beautiful atmosphere and symbolisms abound.
They are not for the faint of heart and offer a memorable experience. Other anime that heavily resemble Mononoke
