Keep squealing, downvoters. Cameron's a technically excellent hack who only cares about special effects, which is why his films have maximal revenue and minimal cultural heft.
I’m not a huge fan of his, and maybe you’re only talking about more recent films, but Terminator and Titanic have more than “minimal cultural heft” as far as Hollywood movies go.
The problem with Terminator is that the plot was lifted (per Cameron's admission!) from an Outer Limits script; besides that, the significant visual was casting Arnold...which Dino DiLaurentiis might've done anyway.
