Movies available were good choices. Seats were extremely uncomfortable, had extreme difficulty exiting seat to get to rest room. This was the bumpiest and roughest plane ride I have ever been on. It felt like the seats were tighter than a few years ago. Food was not very good and the return trip was the absolute worst. Dublin airport had a power outage that caused us to be in lines for 6.5 hours, and we were the last 4 people who made the flight. Also, the landing BOUNCED extremely hard and my husband thought perhaps the wheel was broken off it was so hard.
