This film is consistently funnier and goofier than the first.  There is much action, and most of it is funny action this time around.  You'll see what I mean if you watch the first and second film together.  The Shredder returns, which is good, although they don't explain very well how he could have survived being crushed by a trash compactor.  He sharpens the blades on his costume, altering it some and making him look even more fierce with sharper, more jagged blades.  Tatsu is back, too, somehow escaping the police from the first film.  He's as great of character as ever.  There are a few Foot Soldiers left, and they are on a mission to recruit more.  Shredder and his Foot Clan manage to steal some of the ooze that transformed the Turtles years ago.  He uses it to mutate a wolf and a snapping turtle.  To his dismay, they are babies.  When they mutate into horrible monsters, they are like small children...but very strong.  The snapping turtle's name is Tokka and the wolf's name is Rahzar.  I like these characters, but wonder why they didn't try to include the popular characters from the cartoons Bebop and Rocksteady.  That seemed like a given to me.  At any rate, I love the Tokka and Rahzar characters and they're cute despite the fact that they look monstrous.

    Another new character is added in this movie by the name of Keno.  He's a funny teenager with an incredible talent for martial arts.  Of Asian distraction, Keno is a pizza-delivery boy who happens to discover the Turtles.  He soon becomes their sidekick in the film.  I like Keno a lot.  The writers did a really good job with him as well as the actor who played him.

    What's really neat is that by the end of this film, Shredder mutates himself and becomes the Super Shredder.  Good lord!  How would you like to go up against something like that?  He finally does get killed, though, in no uncertain terms.  This is a fun movie to watch and I recommend it to families.
