Is '24' Shark-proof? Is '24' Shark-proof? No, it has jumped the shark many times, in my book. It's still highly entertaining. Go here to see the exact moment that it may have jumped the shark. I cannot point to a particular moment or scene, but the fact that Jack has died two or three times and chases bad guys immediately after heart attacks and never sleeps, well, that just about proves a little sharky-shark.
