Nonsense. The quality has been crap overall. Way worse than usual.
Im sorry but i have to agree with @bosnian_red
Too much idealization of previous WC around. If you watch highlights compacts of previous WC it looks like winning teams were killing machines but if you follow matches closely i remember that matches are usually very close and a lot of times teams that get to the final rounds have not impressive tournaments at all like argentina 2014, spain 2010 (What a wankfest of a team that was zzzzzzz), italy 2006 etc.
