This is an enjoyable & entertaining movie, with a good cast. I was at first disappointed when Harrison Ford pronounced nuclear as "nuculer". I later reconsidered & thought that maybe it was a joke on the part of Spielberg, one of my all-time favorite directors or someone else involved with the film. However, on reading ALL the goofs in this production, I wonder if it wasn't more sloppiness or lack of attention to detail? My husband & I have seen the previous Indiana Jones films & liked them enough that we looked forward to this one. Crystal Skull was recommended to us, & we would certainly recommend it to other people. But, having seen the two National Treasure movies, one very recently,I think I've had enough of this theme for a while.
