The PA stuff and the marketing is intensely annoying but that's not the crew's fault.
How can it be annoying it not like every announcement cuts into your IFE "now that is annoying".
I simply book print and board, watch the crew do there thing on landing on water then plug my iphone in and watch a move or have some music on, I never hear anything and can see when the drinks trolloy is on it way.
Infact I find Ryanair flights the most relaxing and uninterupted flights there is.
