I also agree with another poster who suggested the old "subtly, every aircraft is different" should make a come back. I still think I could recite that video word for word today - and that's probably a good thing.
Probably because about twenty score and ten people remember that very line you quoted, if they remember anything else. Even Pam Ann knows it like the back of her hand.
I personally don't like that one, especially when it was transplanted to Jetstar, because it gets very long and ridiculous when you run the full checklist style summary at the beginning before launching into the video. The intonation is very, very unnatural - it really is more or less like a robot doing dictation (except a very good one).
That said, the phrasing and sentence flow of some of the last safety videos hasn't been good in parts. The captain who speaks at the beginning (e.g. of the Olympics version of the safety video) - I'm sure he's a great captain and a nice man - but either he's got severe asthma and can't say many words at a time, or he needs to work on speaking more naturally. (Maybe he speaks like that because he speaks very fast naturally, and was told to slow down, especially since ESL people also need to be able to understand him... don't know, guessing now...)
To be honest, some of the best readings of the safety demonstration have been from.... cabin service managers, when the safety video malfunctions and they need to do it manually from script.
I don't mind the taped Virgin Australia safety demo reading... though when I listen to it, why do I keep thinking of those dreaded Demtel ads?
And I'll put $10 down that more Australians know the first verse of our national anthem than they know the meaning and how to use the word, "subtly". And that's a big call.
What's wrong with just saying something like from the safety video that opened with the kid throwing the paper aeroplane, "Each aircraft type is different, so it's important that you pay attention to this safety demonstration." Malaysia Airlines preface their safety demonstration with a PA similar to, "Since safety procedures can vary from aircraft to aircraft, it's important that we have your full attention." And of course we don't need a smart aleck remark a la Virgin Atlantic (paraphrased, with cheesy cartoon), "Even if you fly with us heaps of times (needs to be cheesier than this), it's still important that you watch this safety demo."
