Teenage Mutant Ninja Turtles III... look, I know the movie's awful. It's indefensibly terrible, utter crap, and a complete insult to samurai-era Japan, time travel plots, and the lovely Paige Turco. But it's not as awful as Volume 3 of the comics.
[Reveal] Spoiler: You are better off not knowing this. This is a thing that actually happened.
Raphael gets one of hands cut off. Leonardo loses an eye. Donatello is maimed so badly they have to turn him into a cyborg so he doesn't die. The Turtles kill Shredder, as in "Shredder goes one way, his severed head goes the other way." Raphael puts on Shredder's armor and decides to take up Shredder's mantle.
No wonder Volume 4 decided to say "No, Volume 3 never happened, people know about aliens like the Utrom, the Turtles are middle-aged now, Casey and April got married and have a daughter."
I'm gonna sound equally weird for saying this, but Teenage Mutant Ninja Turtles (2014) actually looks like it's gonna be decent. Yes, it's Michael Bay, so you know it's gonna be mindless stupid action, and yes, it's got Megan Fox who's easy on the eyes but can't act if her career depended on it, but I'm a fan of dumb stupid popcorn fun. (Except Transformers. Those movies are just stupid, stupid, stupid, stupid.)
Tangentially-related fun fact: Every TMNT weapon is statted out in Dungeons & Dragons. Unsurprisingly, the katana is the only one actually worth wielding. (Rather surprisingly, a sai does bludgeoning damage instead of piercing damage as you'd expect.)
