I like these two actors (i.e. The Wedding Singer) but this movie was just plain empty. After a while you tell yourself, \"the whole idea is silly\". It seemed that Adam S. was not really into the role either, just my view.
Shrill, abrasive, cartoonishly over-the-top and badly titled.

It could be that What Love Is is what lovers of either gender can like, thanks to equal parts misogynistic machismo and locker-room girl talk, all of it tied together with just a little bit of cozy romantic reality.
