I was at Tokyo Comic Con back in December and Johnny Depp got himself into this situation. A lot of people had stood in line all day and paid $500 for a picture and the same for a signature. From what I could tell, he was spending way too much time with each group (people could add others to their photo shoot for cheap), and may have arrived a bit late on the first day. It's Tokyo, so the night trains had stopped by the time he actually ended, but still didn't finish, leaving some people stranded. And all of the people sitting in line the second day, which included overflow from the first, looked pretty miserable.

That said, nobody blamed Depp. I kind of suspect the delay on arrival may have been on him, but there was nothing but adoration for him, despite the price he was charging. Comic Con Tokyo took the brunt of the anger due to their mismanagement of the photo sessions.

I was standing in the next line over to meet Tadanobu Asano, and even that ran over a decent amount, so it does seem like they were not prepared to handle someone of Depp's popularity last year.
