the promo (first one, didn't watch the second) needs improvement, for sure. what i hated the most was the echo-effect or whatever you call it. but again, these are made by people who probably don't know much about advertising and making videos. if it was made by ANA itself to promote upcoming convention, that would have been really shameful.
and to those smarta$ses complaining about accent and grammar: nobody is perfect; not even a native speaker. You didn't speak fluent English the moment your mom spit you out, did you? The point is, it takes time to improve English and some may never be able to do it. If you speak good English, good for you. But that doesn't mean you can humiliate not-so-good speakers in a public forum.
