"I loved it!" said the 6 ½ -year-old critic who accompanied me to the screening of the animated adventure "The Smurfs." He had previously explained to me what exactly a Smurf was (a negative dwarf plus a negative elf equals a Smurf, which sounds like a perfectly fine equation to me except that it doesn't explain why they're blue), that Smurfs "can be really not smart," that they are really funny and that "the bad guys always lose and stuff."
