You can't talk about Halle Berry as Storm without talking about the most controversial line in all of X-Men movie history. Some people love it. Most people hate it. Rumors are that Joss Whedon wrote this specific line. Let me paint the scene for you. Storm is fighting Toad on the Statue of Liberty. He's hanging onto a pole by his tongue. Rogue conjures a storm and says, "Do you know what happens to a toad when it's struck by lighting? The same thing that happens to everything else." Then she zaps him.
The line harkens back to the golden age of action movies when heroes would throw out one-liners at every chance they could get. It's not the best one-liner, but given that it's the only one that Storm says, it fails to impress.
