I thought it an excellent installment in the series. It had all the elements we love, action, self-deprecating humor, good byplay between Indy, Marion and Mutt (Great name for the son of a man named after a dog!), exotic scenery, and pushed the envelope by adding the alien angle. Allen gives a very satisfying performance, with less of the sharpness of her original role, but more compassion (she's apparently grown up in the interim--and so has Indy... ). Single greatest moment: the sword fight between Mutt and the Russian villainess, (excellently portrayed by Cate Blanchett) atop speeding (of course) jeeps. LaBeouf was perfect as Mutt, and Ford is ALWAYS perfect as Indy.
