Whilst most air travels are safe, I think it's also important to dim the cabin light during evening takeoff to let the passengers to adjust the eye in the event of an emergency. Today I was flying from NYC and during landing, to my surprise the cabin light was not dimmed. Although during descend, it looks bright outside. Once during the approach, it's dark outside. Whilst the crew wasn't bad per se, although they seem fed up with their job. I don't want them to get into trouble.

If I write to AC about that, what would be their likely consequences?
