Still cant get past the plot hole of having the power switch in a bunker on the other side of the raptor paddock (as for raptors, recent research suggests they were feathered and far smaller than their Hollywood cousins) thus meaning humans had to go through the paddock to switch the power back on. I suppose putting the power bunker underneath the cafeteria for instance would have been stupid in the extreme so I'll shut up.
On the contrary, going to a cupboard in the next room to turn the power back on doesnt do much for the drama.
I'd say it's more dramatic licence that the bunkers were situated where they were. It's an action adventure film afterall.
