What are some of the worst movies you've ever seen?

I watch everything with something that resembles a dinosaur in it, but don't knew Z-Rex existed.

The Valley of Gwangi is something between King Kong and The Beast of Hollow Mountain, this time is an allosaur-tyrannosaur hybrid living in a lost valley with some other animals. Unlike the Beast of Hollow Mountain Gwangi looks quite alive and doesn't resemble a newt from Venus.

Another movie that is just an ordeal to watch is 100 Billion BC.
It's awful. Just garbage.
