I went to the midnight premier here in Australia, and man was it amazing. They had 4 cinemas showing it only minutes apart, and they were all full. The foyer was crowded with people. So many people dressed up as characters, or things like snitches, hipogryphs and someone came as a broom

My friends and I were all dolled up because we had been out for dinner and drinks before hand to celebrate. Even with killing 2 hours over that, we had to wait another four hours before we got to go in.
We had the worst seats, right up the front and smooshed in the corner. But for some reason all the girls in our row decided they wanted to sit in the empty row infront of us, so we lucked out with that and atleast got to sit centered.
Ontop of that, it was an awesome crowd. Just an amazing night. Harry Potter was such a huge part of my life, and I remember going to the very first midnight premier when I was only 9. David Yates has done an amazing job with the Harry Potter franchise.
The only thing that I thought needed working was the character deaths. They could have milked all of them a little more. I still sobbed when you saw fred, tonks and lupin in the great hall, and I still enjoyed the battles with Bellatrix and Voldemort, but they were all lacking.
AND, my biggest surprise was that the 19 years later part wasn't completely awful like I thought it would be. I hated reading it, but they actually did a really fantastic job with it.
Can you tell I'm a fan?
