User blog comment:ReverseZoom101/"Crisis On Earth-X" Plotholes and Easter Eggs!/@comment-32870856-20171210072954

Agreed on the first two plotholes, but the third, your wording has confused me a little. Kara saying that the Dominators "were so last year" was because they literally fought them last year. I don't understand why you believe it's a plothole.
