I didn't think I'd like this movie, and I didn't. I loved it! Gru is a believable character, and the girls are awesome. (Cynical Margo, nightmare fetishist Edith, and adorable Agnes.) This movie is clever, heartwarming (but not in a sickening tastes-like-diabetics way) and laugh-out-loud hilarious. I added the "scary" warning because of Miss Hattie, the runner of the orphanage. She's cruel, heartless,runs a cookie mafia from her orphanage, and makes kids go in the "box of shame." She's evil, irredeemable, and worst of all, she gets away with it all.
However, this movie rocks anyway.
