Sand Castle will likely resonate with general audiences. The acting in it is good for the most part, as Nick Hoult pulls of his part very well. His acting is pretty spot on and the story telling around his character is well done. Logan Marshal-Green did a superb job in his role as a get-it-done SSG who reminded me of a couple different platoon sergeants I'd worked with while in Baghdad. The story itself is fine, and even though the outcome was predictable, I didn't stop rooting for the guys to get it done. Where the movie fell short for me was in the details. Coimbra should have hired a decent military adviser to help him out. A good example is found within the first few seconds of the movie, as Hoult's character strolls to a great tune by Queens of the Stone Age through a staging area in Kuwait (camp New York?) he walks past some tanks that are being readied for combat. M60 tanks. I kid you not. As an M1A1 Tanker myself, I knew at this point there were going to be some obvious flaws-and there are quite a few others-but they didn't really detract from the story. I'd probably recommend this movie to others for the story alone. If you are former military, just know what you are in for.
