Well, I like the interface, it's quite smooth, simple, easy to use and pleasing to the eye (since it basically is following closely to Google's material design thing). Though I will say when clicking on the specific items to view more details, it might be better to have that triggered by clicking either the image or the surrounding text/box that shows the basic information of the show around each entry, rather than only taking you to that page if you click on the cover image. Especially as when you tap outside the image, it still gives a little animation that usually plays in Stock android apps when you click on a button.

It's a small thing, but I actually ended up tapping the whole thing several times, before realizing it only takes you to the page with more information on it if you click the image of the show. Also, you might want to move the little plus button that shows sharing options a bit further up. On Mobile devices, it does look a bit weird that it partially covers the Review tab.

Also, I assume it is a feature to come, but in the Similar tab, with the characters and related anime, you definitely want to let people jump from what they are viewing to one of the related shows (as clicking it down there now does nothing.) Also, you might want to reconsider naming the tab to something other than 'Similar', as it also shows the characters in that tab too.
