Life of Pi's Idiocy

I, Aristotle, just having finished Yann Martel's novel Life of Pi, think that it is one of the worst novels I've ever read. There is no way that a tiger and a man can live on a boat for months together. That is simply impossible. A tiger would sense that the man is food, and would eat him. What an absurd story. Also, the chapters where Pi is living with these magical plants is completely preposterous. Plants and islands can not be carnivorous. I like scientific novels. Hard facts. This fantasy "piece of literature" is just terrible.
