Not exactly. You're in place that people really care about the setlists, people come here to discuss about the setlists, the songs, the intros, the extensions, the transitions and so on.
When you see someone criticizing the setlists, but in his signature you can see that he already purchased three tickets for the upcoming tour - you need to realize one important thing: the discussion here is from each person personal point of view, it doesn't mean he's not going to enjoy the next show, it doesn't mean that he thinks the band is doing something wrong, it just mean that the show isn't 100% (or 90% or 80%) exactly how he want it to be.
There are some stuff that needs to be criticized like shortening/dropping the current single or lack of diversity between the sets - as random examples. Just separate the discussion from the experience.
