From a
similar thread, the answer hasn't changed in 2 years.
Worst concert: Demi Lovato. Her fans are just so ****ing annoying. I was at the end of the catwalk and everyone was like 'What's your favorite song by her?' (I only came to see Give Your Heart A Break and Skyscraper) 'Oh you're so lucky, how did you afford these tickets?'
'Uumm I have a job, so I can afford them. They were pretty cheap compared to some other shows I've been to'.
Then it was stan wars about how 'Madonna is so annoying and I only like the song with Justin Timberlake she isn't as good live as Demi. She tries to be Lady Gaga so much'
**** are you ****ing full on retarded? Yeah she isn't as good as Demi, because she's better. Madonna can run circles around Demi and she made over $7 million when she came to Toronto, Demi would never.
Also during Fire she told us to get up which ended up being so awkward with everyone on the balcony sitting down and singing 'you can't keep my down in my seet' 
And also I was sitting next to two drunken old gays who were so loud and off key it was crazy. The one that was sitting next to me was breathing so heavily, I could always hear/feel him exhaling, I'm pretty sure Leona felt that too. They would also go to the toilet every second song which was annoying af. Oh, and I got this awful stomachache halfway through the show. Nevertheless, she served with vocals and stage presence and I loved it.
I wanna hear reviews from the people who went to ANTI
