Get Out is a very good movie. It is a horror movie and satire (and I thought it managed to pull both off). Jordan Peele's writing and direction are excellent. I do not want to give anything away (beyond the trailer above) other than it definitely skewers spoiled white liberals. I thought Daniel Kaluuya did a fabulous job as the lead actor. The film gets great reviews both from the critics and the audience on Rotten Tomatoes.
Allison Williams is certainly better in this than she was in Girls (although that's a very low threshold)
