Teenage Mutant Ninja Turtles - Trilogy Review 

In the first movie, they showed Donatello's intelligence by him answering the trivial pursuit question with "War and Peace" immediately when asked, where the other turtles became fed up because he was winning at the game so much. They also showed him working on fixing the engine of the truck with Casey at the farm. The final thing was at the beginning and end of the film, he couldn't immediately think of any topical, cool words to say like his brothers, which geniuses often have a hard time relating to others like that.

pretty well know by now id expect, but Super Shredder is played by a guy who later become superstar pro wrestler Big Diesel/Kevin Nash of NWO fame

As a child I loved all 3 movies.
