The dutch played poor tactics and it was a fair result, they were lucky a number of times not to be down to 10 men earlier.
I am not usually a fan of the ref, granted the fact he is a brit helps but you can't spend 115 minutes kicking the spanish around the park and then throw your toys out the pram when you get ever so slightly blocked. He made a couple of off decisions but i think the main one the dutch are moaning about was fair.
