Gal Gadot hosted SNL with the wide-eyed innocence that?s always fun from a first time host. You know, that look that says, ?What have I gotten myself into?? And there were a couple fun moments, but the material just wasn?t there. Now, to be fair, it?s a pretty crummy week to try to come up with something funny ? and Jason Aldean opening the show by covering Tom Petty?s ?I Won?t Back Down? evidenced that.
