With references to House of Wax, Close Encounters of the Third Kind, and George Lucas, the first 30 seconds of DreamWorks' Monsters vs. Aliens makes it clear that the filmmakers wanted to pay homage to their favorite sci-fi films. Thankfully, the genre in-jokes aren't the focal point -- they just provide amusing window dressing so that movie-savvy parents can enjoy this elegantly simple tale as much as their kids. The story centers on Susan (Reese Witherspoon), a bride whose wedding goes spectacularly wrong when she she's hit by a meteor outside the church and proceeds to grow 50 feet tall. Immediately after her transformation, the military swoops in and whisks her away to a detention center for monsters. Among her fellow inmates are the gelatinous, blue B.O.B. (Seth Rogen at his best); the half-insect, half-mad scientist Dr. Cockroach (Hugh Laurie); and the part fish, part human Missing Link (Will Arnett). Although Susan wants her freedom, she's told that this can never happen.
