8 Most God-Awful Movie Superheroes Not Based On Existing Material

6. Sharkboy & Lavagirl - The Adventures of Sharkboy and Lavagirl in 3-D (2005)

Sharkboy Lavagirl Robert Rodriguez must really love his kids. I mean, going be half of his filmography, he must: instead of dedicating his time to making sequels to Sin City, he's spent a large portion of his career making movies for his children, to the point where he even credits them for coming up with the ideas. So did Robert Rodriguez's kid come up with the idea for From Dusk Till Dawn or something, you wonder? No, that's just silly. Sharkboy and Lavagirl in 3-D, on the other hand... Sharkboy and Lavagirl are two characters that Rodriguez' son, Racer, scribbled down one day on a bit of paper. Unlike most fathers, though, Robert Rodriguez didn't acknowledge the creativity and stick in on the fridge or something, he found a way to turn it into a $50 million dollar movie. Okay, so it was aimed at children, so we weren't exactly expecting characters on par with that of Heath Ledger's Joker. But Sharkboy (Taylor Lautner) and Lavagirl (Taylor Dooley) are just the worst. Uncharismatic and annoying as hell, you really wouldn't want this pair to save you.
