Remo Williams: The Adventure Begins (1985) - racist and sexist Kung Fu Panda without the funny parts.
Grumpy Old Men (1993) - the grumpy old men were a bit funny. It was the female characters that I couldn't stand. Also, I don't need to watch this movie. I'll just watch Math Teacher turn into a grumpy old man in thirty years.
The Naked Gun 2 1/2: The Smell of Fear (1991) - I hung in there for ten minutes. Juvenile, childish humor. No part of it was funny in those ten minutes.
The Protector (2005): The fight scenes shook too much that I got nauseous. The editing was so bad. I think they cut out all the plots and moved directly to the fights. So the first ten minutes made no sense. Then I gave up.
