Grade: B+

The verdict: Pushes all the right buttons and pushes them expertly.

There's something in Drew Barrymore that brings out the best in Adam Sandler, and there's something in him that brings out the best in her.

50 First Dates is an almost perfect Valentine's movie. Like the stars' last collaboration, The Wedding Singer, it's charmingly romantic and funny (think chick flick). And like so many of Sandler's lowest-common-denominator comedies, it's suffused with slapstick and gross-out gags (think very-guy Sandler fan).

The setup is sinfully simple. Henry Roth (Sandler) is the sort of guy whose idea of a lasting relationship is one that lasts however long the tourist he's romancing plans to stay in Hawaii. Not exactly a womanizer, he believes an island fling can spice up anyone's vacation. (As we see in an amusing montage of his former dates, the emphasis is on anyone.)

Then he meets Lucy (Barrymore), an adorable art teacher who likes to make little tepees out of her breakfast waffles. Henry is smitten and Lucy certainly seems interested, but there's a hitch: She lost her short-term memory in a car accident. So, much like Bill Murray in Groundhog Day, she repeats the same day over and over. Going to the local cafe for her waffles, reading the same newspaper, painting lilies in the family garage and still being shocked by the ending of The Sixth Sense, which she invariably watches after the nightly dinner of spaghetti and pineapple upside-down cake.
