Porter ruined the movie..
Just a terrible addition. Take him out and you've got a 6.5+ movie (similar to the first). From the moment he tries to restrain Heigl (WHY?) to his stupid screams, to his lucky shooting... just ridiculous.
If there was a Jar Jar Binks of Seagal, Van-Damme, Schwarz, Stallone, action movies... we've got a winner.
Horrible, horrible actor.
