I randomly watched the Scott Pilgrim quick look one night, which led to me hearing the soundtrack. After looking that up on Amazon, I bought it. That, in turn, led to buying the game itself, which is a fine, if occasionally glitchy, piece of work. Now all six volumes of the series are sitting on my shelf waiting to be read, and I've ordered a Plumtree shirt in order to dress up on Halloween. 
 
Deep end, I have indeed gone off thee.
