bealine agreed, an interesting clip, but I feel your judgement on the crew is a little harsh - hindsight being 20/20 and so on...
Cabin crew procedures require that evacuation flow be maintained, without halting it unecessarily for various transgressions: Every time you stop to try and remove items, you slow and/or stop the flow. It is an individual judgement as to when a problem is significant enough to actually halt the evac flow.
I hold no brief for Iberia, and am unaware of the specifics of the incident. However I do know enough to know that making post incident judgements about the performance of the Crew based on an internet streamed amateur video would normally be considered unwise.
