I haven't seen The Happening, but I wouldn't say that about Mark Wahlberg. It might not have been one of his better performances, but he's had some good ones in other movies, like Boogie Nights and The Departed.
like i said, i havent seen The Departed, but ive seen most of Mark Wahlberg's movies, and in my opinion, he's an aweful actor, i will never see another movie he is in. but for The Happening, he wasnt the only thing bad about that movie, the EVERYTHING was aweful, im very sick of M Night (cant spell his last name). everyone's acting was bad in the movie, the story was aweful, every scene was terribly framed and shot.
in one place, they show a BIG CLOSE UP of Leguizamo's face, and thats not a face that needs such a huge close up.
ps, Wahlberg is a douche
