These monsters got a ton of problems indeed!  While the intro reminds me of the animated film  Monsters Inc. ,  it  also turns out that  these monsters have a lot to learn in the scaring department!  The  scarers resorted to a banter fit for  school buddies  who seem to make fun of each other's flaws.  Great cast,  the zombie lady was commendable but the surprise best performance was by the child's father.  Not your usual horror film though (wink!)
