DN under Wolodarski has received a lot of criticism, which I suspect you are actually aware of. Please find a few examples below.
Aftonbladet: Journalists question the truthfulness of a series of DN's articles: http://www.aftonbladet.se/kultur/article23755207.ab
Alice Teodorescu of GP has criticised DN and their journalistic methods on numerous occasions, e.g. "DN on collision course with reality": http://www.gp.se/ledare/teodorescu-dn-p%C3%A5-kollisionskurs... Also worth seeing: https://www.youtube.com/watch?v=GRivdUJO1ls
National economist Tino Sanandaji often uncovers errors in DN's journalism, e.g. this example of DN using incorrect statistics: http://tino.us/2014/06/p1-medier-granskar-dn-dn-star-bakom-h...
