Have a quick read of the following articles;
TWA Flight 843 (long standing experienced crew)
Ryanair cabin crew struggles to open doors on burning plane - Times Online (new inadequately trained crew)
The first article have a read about, it contains detailed descriptions of how the passengers reacted and how the crew had to deal with some challenging situations both inside and outside the cabin.
Personally i don't think there is enough training on the actual evacuation process its self.
Yes we all know the processes of an evacuation, but there is very little time spent on using real life examples such as the above, which show in great detail the challenges that actually happen.
Manuals are literally black and white, crew are left fairly much to their own devices to colour the rest in should they need it.
