They put those warnings on 5 gallon buckets for a reason! A few inches is enough to drown in, they keep saying. I've only seen Sixth Sense and TLA otherwise.

Ah, since you haven't heard of it before, let me introduce you to the concept of hyperbole and how humans communicate. Sometimes they exaggerate things. It happens so often that there's a word for it.

But this is not an exaggeration. I've seen Son of the Mask and would rather rewatch that than Signs. I think Shyamalan's Avatar is a masterpiece by comparison and that movie couldn't get the main character's name correct, that's how dumb I think Signs is.
