But SS to me is so near and dear to my heart I can't help but want to write it just perfect, you know?
Oh, I understand you completely.
When you're writing a fanfic about a show (or movie, or whatever) that's so near and dear to your heart, you want it to be just perfect for you, while at the same time, you want it to be just perfect so other fans who will read will be like "Wow, that should've been an episode", "I could that really happening", "So-and-so is SPOT ON", etc.
I feel the same way, and believe me, you learn from your mistakes as you go on; when I started watching
Bewitched back in 2003, I THOUGHT I had watched enough to understand each character, but I was wrong, and my fanfics reflected that when comments I earned were along the lines of "Why would Samantha do that?" or "Darrin would NEVER do that to Samantha", but the more I watched the show, and the bigger fan I became of it, was reflected in my fanfics, as people started praising more and more, and calling out mistakes less and less; heck, at one point, one story I wrote won an award at a
Bewitched fansite because the webmistress felt it was well-written, and very true to the show, while completely original at the same time. Unfortunately, none of those stories exist anymore.
