I dont agree, yea the men's game is more equal but thats mainly because the men's volleyball relies more on height and power then womens which most of the guys from all teams have anyway and mens volleybal is much faster and more easy kills then women who have rallies all the time.
Yes Serbia vs Belgium and Serbia vs Turkey was boring. But both of these teams are not with main squad plus Turkey has a new coach and a new system. Belgium roster looked very weak and keep in mind Serbia beat Brazil quite easily too. They are much better then any team here atm (except maybe China) so I dont think its fair to base the level on the tournament on those matches. Serbia even not at their best is still a very powerful team.
Have you been watching the other matches, yes it may not all be best squads but RUS-USA RUS-CHN JPN-DOM JPN-THA (except DOM incident) were some highly enjoyable matches just to name a few. Im personally very excited and cant wait for upcoming 4 weeks. Serbia is the only overpowered team at the moment but we have to live with that
