One thing that really annoyed me (and many other parents from what I was hearing) was the in-flight entertainment that Aer Lingus provided on our flight to the US. The movie was the Dukes of Hazzard, which even without sound was unsuitable for children. The movie was only a part of problem. Most of the rest of the programming that Aer Lingus provided - with no means of escaping the visual onslaught - was equally inappropriate.
I've never understood why airlines feel they must always show a recent release, no matter how bad it is, rather than an older classic movie. Given that we were traveling during the Christmas period, I don't understand why Aer Lingus couldn't have shown Miracle of 34th Street or some such movie.
