[Terminator 2] Why did the T-1000 need to open the elevator doors? Why not just seep through?

Liquefying requires more processing power than moving as a solid object. That's why gunshots temporarily stun it; it doesn't feel pain, it just has to spend some of its "murder the shit of out John Connor" CPU cycles to molding itself back into shape.

Because of this, unless there's a reason why moving as a liquid is necessary (like passing through the locked, grated door in *T2*), the T-1000 is programed to prefer moving as a solid.
