Alas, dear author, I have some minor issues. Not flames, but critiques. Its too late to change the story, as its already probably finished- BUT a review isnt a review if I cannot be honest. If restricted to being ONLY positive, it is merely flattery.
That said, its good.
I like a smart harry and a pranky hermione. They seem to get things their way a little too easy for narrative tension to really be there, but I kinda understand that your re-doing their lifes how you would have liked them to be- enjoyable and successfull. That doesnt mean that other things can be ignored though..
The first chapter or two annoyed me, as your 4-10 year olds seemed far to intelligent and good at communication. The fact that they said "mean" instead of hurtfull or spitefull doesnt negate that they usually used proper sentences, and waited for people to stop talking, etc.
At school however, their current language seems appropriate, if a little mature. Never forget that theyre only 11 yrs old!
Sadly, you cheapened Legilimency and Occlumency hugely. Everyone knew about it, whereas in canon its a specialised, obscure and relatively unknown branch of magic- even for adults. And then you made everyone learn how to do occlumency, which just made it "common". Its a speciality- its a rarity- its damned hard and whilst canon-harry is disadvantaged by snape- canon harry is also tremdously strong willed and talented. Not everyone should be able to just pick it up.
Finally, you portrayed legilimency as mind-rape, but overlooked the fact that "reading" someones eyes is one of the oldest forms of communication. Legilimency is primarily about discerning emotions and intentions- it only becomes truly invasive with the incantation "legilimens". I understand that Voldemorts use of it is horrible- but hes Voldemort- he makes everything horrible. Dumbledore doesnt push on minds- he X-rays them.
Benevolently! Finally, and I'll have to accept your prerogative in grossly misrepresenting Dumbledore and distorting/multiplying/expanding the petty nastyness of Snape- But it makes me dislike a fic that I might otherwise enjoy.
I hope that you were "big" enough to read this. If you have then, congradulations- you can accept the existence of critism. Thats important. And good
(also something that Dumbledore DOES do, gosh!)
