A video essay has been making in Internet rounds in the last couple weeks which dissects the "emotional closeup" which is a common thread in Spielberg's blockbusters over the last 30 years. The creator of the video is Kevin B. Lee and he acknowledges his inspiration was an article by Matt Patches earlier this year about the "Spielberg face".
If you can get past the semi-funny sounding name of this phenomenon, it's a truly fascinating look at Spielberg's signature move and even how it has even evolved in his films post-9/11. The piece also offer a spirited argument in favor of the director's much-maligned A.I., a film which I also would argue is the director's misunderstood masterwork.
