I like the EU, as you will see clearly when looking at my profile.
It surely has various disadvantages, such as its huge bureaucracy or the massive bribing that has occured. But without the EU and its ancestors, Europeans would probably be shooting each other again.
I'd love to see the "United States of Europe" come into existence, but I think this will take more than a man's age if it is to happen. At the moment, there are far more regional issues than European issues that people are interested in. Best proof is the extremely low participation in the elections for the EU parliament.
At the moment, the EU still is an economical union, hardly a political one. Again, in case this is to change, it will take a long time; just have a look at the British, for example. They are living happily, on their islands, with their rebate, with their feeling of superiority. In my personal opinion, they're acting rather foolishly; not trying to profite from the opportunities the EU offers, but trying to be isolated.
