e-Learning in the Air?

From Sharon, 

"This article talks about airlines and their safety videos, and whether videos that are super entertaining actually distract people from learning the information. 

I think it's very relevant to e-learning - that too much eye-candy, while it looks good, can distract the learning experience. Where is the line between boring training (and nobody listens) and too entertaining (where people listen but don't learn anything)? We need to find a balance."
