You've got to try pretty hard to make a movie with a plot line as pathetic as A Lot Like Love's. When the premise for a film is a guy and a girl randomly staring at each other in the airport, fucking the shit out of each other in the airplane's bathroom and then "randomly" meeting on a New York street corner within five minutes, something is seriously wrong. Twenty minutes into the film you'll hope that Ashton Kutcher will come out and screan that you were "punk'd."
If you want to see the film for Amanda Peet, it's better to rent that movie with her, Jack Nicholson and Diane Keaton about bitter middle-aged writers instead of wasting your time and energy on A Lot Like Love. Peet's hotness is overshadowed by her awful haircut for the first portion of the film.
Unless you're a suburban white female between the ages of 11 and 15, you're better off if you stay home and watch some Punk'd reruns.
