I ventured into the land where many fear to tread, armed with nothing but a hefty 2x4, that most horribly dark pit of darkness...Fanfiction.net...And it turned out pretty much like I expected. Mary-Sue fics left, right and centre, but strangely not that much slash. For which I am eternally grateful.
(My name is Moose, by the way. I shake you warmly by the hand. 'Tis a pleasure to be here.)
BUT! There were some fics that weren't horrible! Mostly the ones based on the earlier movie. Hmmm. There's a fun parody of Wonka-Sue's in general here... http://www.fanfiction.net/s/2524874/1/
An awesome explanation of that weird half-room in the '71 movie here...http://www.fanfiction.net/s/2518908/1/
And a silly little poem about why we fangirl Wonka (despite his many faults) here... http://www.fanfiction.net/s/2542986/1/
That's my contribution to the nearly microscopic fund of good stuff here. I'll keep an eyeball out for more, though, mebbe we can bring light back to the fandom.
