There were a few missed medal chances and especially in the beginning some unfortunate things: CommunicationGate at the women's road race, one of the BMX favourites injuring his knee due to a crossing official (but yeah, then he won gold, so there's that), the whole mess against the rowing team, who still got a big medal haul despite being pushed down and down. But then again, if you've got at least 20 events with a serious medal chance, you're absolutely going to have events where you'll miss the medals.
It won't mean anything for those who missed the medals, because for them it's about their medal and not someone else's, but in general the Dutch team performed incredibly well. Yes, in terms of overall medals, realistic expections were that Sydney's record of 25 medals would be shattered, so it's not a surprise at all in that sense, but it still has to...you know, happen! Even double digit gold medals for only the second time ever, behind Sydney when there were two swimming superstars, and medals in nearly a third of all sports (like in Rio), that is seriously good.
The judo team underperformed immensely, which no sport will make up for as far as how they feel about it of course, but the athletics team...wow. I was realistically counting on 4-5 medals - including a gold or potentially two - if things worked well as a whole, which would've already been an incredible and historical achievement. But EIGHT athletics medals?! Sure, if really every significant possibility worked out well, who knows.
As for my favourite Dutch medals (there are plenty non-Dutch among my favourites of course):
Niek Kimmann's BMX gold after he injured his knee due to an official and after the semis in the hour before that went almost as dramatically bad as it could have gone for the Dutch team, except Kimmann.
The 4x400m men running to silver, I truly never expected a Dutch team in that event being anywhere near the medals, despite their earlier achievements this year, and they wind up with the races of their lifetimes and achieve something so amazing.
Abdi Nageeye's marathon silver, 41 years after Gerard Nijboer took silver in Moscow (in a much weaker field and much easier race, according to Nijboer himself), and while guiding his long-time friend Bashir Abdi to the Olympic podium with him!

I'm going for 8/10, because the total medal haul was slightly less than realistically expected (albeit not much, hence the 8), but there were a whole lot of really good performances including those just outside the medals - think triathlon, for example.
