They obviously had a nice relationship, and his adoptive father was a selfless guy (after all, he died because he wanted to save the family dog from the truck). But still, Clark Kent could have absolutely went and saved his father from the tornado without being seen. He's Superman, after all!

Batman v Superman: Dawn of Justice

This movie is such a fever dream, most superfans choose to not remember it. In this particularly weird scene, Batman and Superman are dueling it out. Just as Batman is about to deal the final blow, Superman comes out with a plot twist. 

As Superman is basically dying, he says the word, "Martha." He was calling out for his mother, which, here's the plot twist... that's also Batman's mother's name! How lucky, because that causes Batman to spiral into thinking about his mother which helped Superman get out of his deadly grasp. Sure, that would totally happen. Needless to say, fans weren't pleased with this easy escape.

Dolittle

Dolittle was not a high point for the infamous Robert Downey Jr. Most would consider it a flop for the Iron Man legend. It's also gotten some pretty bad reviews, especially for its rather dull ending.
