Summer is a hard time with kids because they will eventually run out of your stuff to break, and sending them outside in this heat technically counts as torture. Movies are a good alternative, but they ain't getting any cheaper. Except at Studio Movie Grill. Their Children's Summer Series is offering a great deal; one show a day costs just $1 per kid and $2 per adult to view one modern kid's classic after another. This week you can experience Shrek, the tale of a grumpy fairy-tale ogre who finds love that became the hit that put DreamWorks back on the map as a maker of animated films. ''Judging by the number of times we're asked to bring it back to the summer series, I would say it could be considered a modern classic: It appeals to kids and their parents with a classic story and characters that many may already know,'' said Lynna McQuaker, the head of alternate programming. ''The film barely misses a beat when seen repeated times. It may even be enhanced by multiple viewings, seeing your favorite parts and surprising you with things you missed. I know, at a certain age, my children loved to see their favorite films over and over again.'' Good thing they run it all week!
