Warp Drives are solutions of the Einstein Field Equations that allows superluminal travel within the framework of General Relativity. There are at the present moment two known solutions: The Alcubierre warp drive discovered in $1994$ and the Natario warp drive discovered in $2001$. The major drawback concerning warp drives is the huge amount of negative energy able to sustain the warp bubble.In order to perform an interstellar space travel to a "nearby" star at $22$ light-years away with $3$ potential habitable exo-planets(Gliese $667C$) at superluminal speeds in a reasonable amount of time a ship must attain a speed of about $200$ times faster than light.However the negative energy density at such a speed is directly proportional to the factor $10^{48}$ which is $1.000.000.000.000.000.000.000.000$ times bigger in magnitude than the mass of the planet Earth!! We introduce here a shape function that defines the Natario warp drive as an excellent candidate to low the negative energy density requirements from $10^{48}$ to affordable levels.We also discuss other warp drive drawbacks:collisions with hazardous interstellar matter(asteroids or comets) that may happen in a real interstellar travel from Earth to Gliese $667C$ and Horizons(causally disconnected portions of spacetime).We terminate this work with a description of the star system Gliese $667C$
