The EU lost the country that contributed the less to the Union, and as a matter of fact hijacked a lot of good EU resolutions.
The Brexit can stimulate now a real change into the EU, with EU bureaucrats knowing now that the EU isn't granted.
Companies that moved to London to pay less taxes are coming back, and some UK companies are also moving out, so that's more jobs for EU citizens.
Now that moving to Britain will recquire a visa, EU citizens may choose other EU countries to do some tourism, so other localities will have more tourists.
This hole Brexit vote gives the world another great example of how the people will often vote against their own interest. I really loved to see Brexiters admitting they lied in many cases and abandoning to lead the country after the shitload they created.
Brexit has produced a significant raise of the EU image in EU main countries, and raised awareness about what is the EU across the union. http://www.lemonde.fr/europe/article/2016/07/15/le-brexit-provoque-un-regain-du-sentiment-europeen_4969720_3214.html

Game of Thrones receive EU funds, so the series can potentially be affected by the Brexit as some sets are in the UK.
