The popstar, actress and American Idol judge (who hasn't had a hit movie since she was "Jenny From The Block") swaps her on-stage swagger for serious-teacher glasses as Claire — a newly separated teacher who falls into the 19-year-old arms of Noah (played by Ryan Guzman.)
But the high school student quickly morphs into a stalker after JLo agrees to help him with his chicken. Then, the "movie shifts from ominous to obvious at light speed," says CBC film critic Eli Glasner.
"[It's] the kind of film that flunks even the most basic requirements," says Glasner who censures the film for its "ham-fisted storytelling and lack of tension."
The Boy Next Door is in theatres now.
