I went to the midnight screening, 17 of 21 shows sold out by 10 pm (thankfully I ordered tickets online waaaaaay in advance), I didn't go to find a seat until around 11, at which point the theater was nearly full....and still got good seats 😄
I wasn't at all disappointed in it, and I went in completely and totally spoiled -- I knew everything that was supposed to happen 😛 only thing that might have disappointed me were the scenes that were cut or shorthened.
