The Incredible - Instead of his whole family being super, it's just him. He's hidden his identity his whole life and is killed by Syndrome trying to reclaim his glory days because there's no one to come help him.

Dead Poet Society - Just the sad story about the one guy who kills himself

One Samurai - Weeb who thinks he's a Samurai tries to defend the innocent. Gets killed on his first attempt.

The Magnificent One (so many thing this could turn the movie into but I choose to believe it'll end up about some religious figure)

Ghostbuster - Just Bill Murray being a quack scientist the whole time, or maybe Egon having a fruitless search for ghosts

One (previously Seven) - A documentary about some billionaire who thinks they're special and the only one who can save the world.

Star War - Stops after the first movie. Wait, this may make it better.

Teenage Mutant Ninja Turtle - It's just the scientist on his quest to make the first turtle

The Musketeer - Given this movie exists and I doubt many people who watched it could even tell you what it was about, speaks for itself

Transformer - Documentary about the making of the first electrical transformer.

Tremor - becomes a movie about an earthquake that happens in Perfection. Destroys the few buildings in town and they are forced to rebuild or move.

X-man - Story of the last person in the X-men group, basically a rehash of Logan.

The Warrior - Yet another story about some special person in the distant past who's a great fighter or saves his village from some bandits.
