Ok - so serious reply.
I'm not surprised to see this topic appearing here because social media has been awash with people regretting the lack of soul-searching in the EU.
Well, it's fair to say that most of the serious EU press haven't been doing any soul searching in English .... but they have been doing it in French, German and probably other languages too.
For example, here is a Le Monde take on what Brexit means for the EU - the headline means "Europe is getting better"

"le Brexit n’a pas fait d’émules parmi les Etats de l’UE. Selon lui, les Vingt-sept, par leur fermeté, ont même gagné en crédibilité."
[Brexit didn't have any imitators among EU member states. The 27 even gained in credibility by being intransigent]
Other discussion is more triumphalist, especially in France, which has its eyes firmly set on market share gains in financial services & battery electric vehicles.
You might want the EU to be trembling in its boots but it's not. The second largest member of the single market has gone, and now the remaining 27 are jockeying to take the UK's market share.
