How do you know if you should see How Do You Know? Just ask me.
Great cast: Reese Witherspoon who just lights up the screen, Paul Rudd who's adorably appealing, Owen Wilson who's fine, just not one of my favorites, and Jack Nicholson who's...well, Jack Nicholson. You can't fault the performances, they all did a great job with what they had to work with. Problem was the hugely inane, implausible script, and the direction.
Bad, bad, bad movie.
A waste of money, talent and MY TIME, even to review it.
Zero stars out of five for How Do You Know.
