That was an amazing strip. Rendered me speechless for hours as I tried to come up with something to say. It wasn'y my Shepard but I didn't give a damn because, in the end, they are all Shepards of various universes. They just happen to have the same ending.
As for fanfiction in general, I've never seen it as a place to disrespect the source material but more as a homage, a fine example of "imitation is the greatest form of flattery." Doesn't mean that the writers are better, or worse, than those who original created the material, only that they want to create something more and show their own love for it through creative writing/drawing. Not to mention that fanfiction is hardly a new concept; we have tropes for a reason.
