I also hate The Dark Knight with a passion. I don't care what his fanboys claim, Heath Ledger couldn't act to save his life.
Oh, if we're going on about disbelief... I have to mention Reign of Fire. Dragons, powerful and mighty take over the world. But in the end, it's the lowly crossbow in the hands of an unlikely hero that saves the world. Really? That's a shame I'll never get that time back.
