One of my favorite things in this anime that isn't normally noticed, is that every character has a different eye color. It's so easy to separate the characters based on their eye colors and it's a great way to distinguish characters.
I love the way that you get to peek inside Oreki's mind and see how it works. He's so overwhelmed with the daily tasks and it shows. It shows how much he truly is amazed by Chitanda and Satoshi and sometimes by Mayaka. The show is well thought out and develops greatly over time.
One of my all time favorite animes ever. I love it. I recommend it to anyone. Amazing. Perfect score all around.
