As for the complaints, ever since Projector first leaked, every time a new Dark Tranquillity album hits the net, people have complained on the forum. It would seem that every new album of theirs receives plenty of harsh criticism (and only some of it well articulated) from some old fans even before it is officially received.
Look, I'm an "old" DT fan - I remember back in '97 opening up my copy of the Mind's I on Christmas Day, putting it in my CD player, and being FLOORED! (I was a mere 14 back then and I've like DT for more than a third of my life.)
Anyway, I just wanted to take the opportunity to comment on Projector and on the "old" fans some of whom have turned into the most stupid "critics."
I'm not the biggest fan of the album. There were some amazing tracks and more than a few that I didn't care much for, but the album was a breakthrough in terms of DT's artistic direction. After the Mind's I, I was worried they'd get stuck in a creative rut. After all, how could they top the Mind's I and the Gallery? Where could they go? So I for one was relieved when they undertook a bold experiment in their sound by incorporating Stanne's amazing clean vocals and electronic elements. The overwhelming majority of good/excellent metal bands do not venture in bold new directions once they've established themselves and made themselves comfortable with a certain sound, either because they are afraid, they don't care to evolve or change because "if it ain't broke, don't fix it," or whatever.
Projector was a turning point for DT. It marks the end of the DT's middle stage (which I would say spans from Skydancer/Of Chaos to the Mind's I, while the early DT was pre-Skydancer) and the beginning of what I consider their mature stage.
The stupid critics would rather DT stagnate and produce the same album(s) over and over and over again and that's why I can't stand their criticism. If DT actually made a bad/crappy/lame album, I would be the first to say so. But I'm very happy that they are growing, changing, and evolving while still retaining their trademark sound. There is both change and continuity, and the music has become more rich as a result.
To me, Fiction is as much a classic as the Mind's I or the Gallery. Character and Haven were both good (Damage Done was excellent), but I really do think they have managed to create a flawless masterpiece this time. Of course there are fans who will disagree with me on this, but unfortunately a lot of the criticism of Fiction has been extremely shallow, stupid, and impressionistic. If you want to criticize, at least have some good arguments and points to make.
And Villain, you forgot a fourth possibility: they are just idiots, plain and simple.
