Drew Barrymore nailed the accent of the "Long Island Lolita", Amy Fisher, the seductive and troubled teen who was sexually abused as a child and falls in love with Joseph "Joey" Buttafuoco and seduces him into a sexual relationship after meeting him by crashing her car, and crashing it over and over and over again as an excuse to see him. She becomes obsessed with him, and while she respects his wife and the fact that he has a happy family, decides to attempt and kill his wife so she can be with him.
Drew Barrymore's incredible performance makes you sympathize with Amy, and makes you wonder if she had had a normal life and hadn't felt so trapped in her house her whole life, maybe she wouldn't be so screwed up. Awesome script, awesome movie, you can tell the director and writer put a ton of work into making it perfect,
