I remember when the first live action Teenage Mutant Ninja Turtles movie came out; most people probably thought it was going to be a live action version of the cartoon show not the original black and white comic books that Kevin Eastman and Peter Laird created back in 1984. So it threw people for the loop when the turtles didnt have the arm and knee pads that match their mask color like from the show, the turtles personalities were slightly different from the series i.e. Mikey wasnt speaking like a surfer dude, Raph was always seem angry at the world, The Shredder wasnt some bumbling villain that would trip over his cape and he was capable of beating all four turtles on his own. Not to mention the foot ninjas were humans not robots and there was no Krang or Bebop and Rocksteady yet you do have cheaper versions of them in TMNT 2: secret of the ooze but thats another story. Plus the turtles and Splinter s origin was completely different from the show, before the movie people thought Shredder dump the ooze that turned Splinter from a human man into a giant rat, instead of the origin story the old comics have.
