Well, I just got back from seeing it a couple of hours ago. Sam Jackson was in his element. The snakes didn't even have a chance once a bad *** mother ****er like Samuel L. Jackson got on the plane.
Here's my synopsis:
A kid named Sean Jones is riding his dirt bike in Hawaii when he stops and sees an LA District Attorney get beat to death with a bat by the villian in the movie, Eddie Kim. He runs home and hides. The bad guys find him. Sam Jackson, FBI Agent Nelville Flynn, shows up just in time to kill some bad guys, grab the kid, and run. Jackson tells Sean that he dead if he doesn't testify. He finally agree after a little classic Jackson finesse. Kim's got people in the Hawaii police, so they decide to fake out Kim by not putting him on a government jet. Instead they put him on a commercial flight. Kim's got men working at the airport who are ready for this and tip him off when they figure out which flight they're going to be on. The get in the air and everything is fine for a while... They sprayed the plane with snake pheromone before they took off, and when the snakes are finally set loose, they go ape ****. They kill about half the passengers in a non-stop blood bath for about five minutes. They finally manage to contain the snakes in the back half of the plane. They regroup and at this point they've lost one of the FBI agents and one of the 0pilots. The remaining one is hilarious, though. They're able to contact the mainland, and the FBI there is able to find a snake expert. The remaining pilot get nailed by a Cobra and is seemingly dead. The plane goes into a nose dive and it's up to Sam Jackson to pull them out of it. This also causes the snakes in the back to get thrown into the front. Another half of the passengers die, and the rest head into the top level of the plane. They pull out of the nose dive and the seemingly dead pilot shows up to pilot the plane again. The ventilation system dies and only Sam Jackson can fix it. He goes into the cargo hold to do it and kills some more snakes while he's down there. He gets it started again just in time to find out the pilot is dead, for sure this time. The cockpit is now swarming with snakes and they're almost to LA. Jackson decides the get the snake out of the plane by shoot a hole in the plane and venting them out of the plane. Of course, half the passengers and crew aren't properly secured and nearly fly out the side of the plane. Jackson and a guy who learned to fly on his play station land the plane. Everyone else survives, and they live happily ever after.
