I’ve not watched The Avengers, but I would absolutely love to see The Horcruxers in action. Harry and Severus look so dapper and appealing - very shaggable, what with their flirty expressions. Oh, those eyes! And I like that there are two different sides to behold of each man, giving the characters more depth.
The retro style is very charming. I love the pale colours in the background, and the bubbles are fabulous.
