Query: A Deranged Masterpiece

A movie so inventive and funny, I'd suffer through the entire Adam Sandler filmography if they'd let me see it again (except "Bulletproof", of course). Especially memorable: what happens when JM enters his own "portal" and the surprising turn of events when Craig (John Cusack) manipulates JM for his own benefit. It's so refreshing to see a movie devoid of that "Test Audience Mentality". My sole regret is that I knew anything about the plot before seeing it.
