I would not call it a nightmare, just a lot of information to be aware of before starting. Although at times EASA and some of the national CAAs of Europe will make you appreciate the efficiency of the FAA (how many times do you hear that about a U.S. government agency).

IMHO the simplest route to go is to do the ATPL theory exams in the UK and do the medical and skills test/license issue through Ireland.

It can seem daunting at first, but once it is over you'll have a great sense of accomplishment. Plus if you have the unlimited right to live and work in Europe, a lot more doors will be open to you. European jobs do not pay as much as the States, but I much prefer the quality of life in Europe to that of the States. But to each his/her own.
