First, it looks like it pretty much sucks. Also, it stars bongo-playing hippie pothead Matthew McConnaghey and Kate Hudson, who is a genetic duplicate of an actress who has spent the last 30 years annoying me. I hoped that age and death would eventually rid me of Goldie Hawn, but no.
Second, its premise is absurd. No one would pay a freelance writer to do an article on how to lose a guy in 10 days. That would be like writing an article on how to breathe oxygen in order to avoid death, or how to propel yourself forward by making walking movements with your legs. Everyone knows how to do this; it's the easiest thing in the world. An article explaining how to lose a guy in 10 minutes would be overkill.
Third, every time I see an article about it (which I do a lot, given that it is inexplicably the most popular movie in America), they abbreviate it "How to Lose a Guy", and my stupid mind converts it to "How to Roll a Blunt", and so now I have that particular Redman ode to the zooted stuck in my head.
