Another point of irony about the 90s movie Shredder is that while he's considered one of the most menacing portrayals, when you step back and look at it, even the 80s cartoon was probably more powerful. The film Shredder was portrayed awesome, but what was his ultimate ambition? To get a bunch of street kids high and get them to play ninja, stealing him stuff off the streets. The cartoon Shredder (in either the 80s or 2000s)? To take over the world. The comics? I guess to avenge his brother?
Either way, despite such an awesome, terrifying portrayal of the villain, you have to admit his big villainous plot in the big picture was kind of goofy.
