I don't think the patterns per se are the problem, but rather the fact that developers can learn patterns and then overapply them, or apply them in ways that are wildly inappropriate.
The use of patterns is something that experienced programmers just learn naturally. You've solved some problem X many times, you know what approach works, you use that approach because your skill and experience tell you it's appropriate. That's a pattern, and it's okay.
But it's equally possible for a programmer who's less skilled to find one way to do things and try to cram every problem they come across into that mold, because they don't know any other way. That's a pattern too, and it's evil.
