James Cameron has created some of the greatest action movies of all time. Rambo: First Blood, one of the raddest action films ever made. Aliens, the only Alien sequel to be on the same level as the haunting original.
The Terminator, an incredibly awesome film with Arnold Schwarzenegger's best role yet; as well as Terminator 2.
Hell, even the awesomely bad Piranha 2.
His only miss to date was probably Titanic.
