I'm 25 and live in the UK. I'm rather notorious for going off on rants about book to film translation and poor character depth (not exclusive to the HP universe). I really really hate the Harry potter films. I wasn't very impressed with the last 3 books, and then I found fan fiction...
Slytherins Secret is my addition to the wonderful world of Harry Potter AUs where he wakes up and gets a clue. I'm going to attempt to make him subtle and have changes pass under the radar where I can. Hopefully he won't end up too powerful, and I expect in a lot of ways I will follow canon major events.
As far as fan fiction goes I love manipulative Dumbledore, though how dark varies, Snape and Draco can be good or evil so long as it's properly characterised, there's certainly enough justification for either in canon. Ron and Hermione can be anything from paid spies to the most loyal of friends, and the same goes for the rest of the Weasleys. I love Neville and Luna and wish they had had some character development in canon.
Fell free to review in great detail I need all the help I can get :)
