I will give a review of Kamisama when I finish watching the third episode. As for first impressions, the intro art was really good. I remember seeing screenies on another blog and thought the colour choices was a bit faded but nice. I have to say the same with Kimi ni Todoke - the colour choices aren't a vibrant HD - but it gives everything a nostalgic feeling. Which I think is fitting for older audiences reminiscing about high school times.
Nice colours right? Like taken from an old camera
