I wondered how movie makers would turn a relationship guide into a successful hit movie...and I never found out...because this movie was lacking. I'm just not that into it. A couple of years ago, I bought Greg Behrendt's book ("He's Just Not That into You") and absolutely LOVED it! It offered good advice and was funny as well.Unfortunately, none of that transferred to the big screen. Everybody got the story line; so, it became boring watching so many of the same examples of women simply not understanding when a man is just not that into them. When a person doesn't (1) call, (2) return calls, (3) act interested, 4) make time to see you, etc., it's because he/she is not interested. Period.After a while, the movie seemed to drag on endlessly. So, as much as I loved the book, I did not enjoy the movie enough to buy the DVD. I may watch it when it comes on cable...unless I have laundry to do. LOL!
