Just saw it, and feel really depressed now, not because I didn't like it - I thought it was amazing - just that it's all over now. It's been like a constant in my life for the past decade or so, like my whole childhood.
I lolled so much though when it showed the memory of Snape hugging Lilly's body. Don't know why, just couldn't stop!
Now I feel the urge to re-read all the books. Feel empty now tbh! Nothing to look forward to, and never going to be able to look forward to the next book or film being released. DEPRESSED.
EDIT: For all the people nitpicking, of course it wasn't going to be detail-perfect. I think they adapted it excellently for a visual conclusion!
