TMNT: When will these teenagers finally grow up?

Beautiful New York City is under attack once again by a villainous gang, this time by Nickelodeon’s hand.  The malevolent Shredder has taken control of the city with his helpful Foot Clan. It is left to four ninja turtles, with personalities of their own to save the day. New York just can’t get a break.
In “Teenage Mutant Ninja Turtles,” New York City reporter April O’Neil (Megan Fox) is trying to make her debut with a big story. Witnessing a Foot Clan crime and vigilante attack in action, she decides to get her story by recording the attack and the vigilantes. Imagine her surprise when she saw six-foot tall turtles. Sooner than later she realizes she knew Leonardo, Rafael, Michelangelo and Donatello all along. She also comes to find out Shredder’s toxic plan for New York City.
It was clear the turtles were teenagers — or young adults at least­ — riding skateboards and childish girl obsessions. There was Leonardo, the leader; Rafael, the aggressor; Michelangelo, the immature one; and Donatello, the science techie.
The movie did become questionable as to whom this movie was about: April O’Neil or the turtles? The story became revolved around Megan Fox becoming the hero and the damsel in distress. O’Neil was not supposed to be as dramatic of character that Fox perceived her to be. It is understandable they’re teenagers, but they were teenagers in the 90’s. When will they grow up? Perhaps in the sequel the humor will correspond with their age.
