“Approaching The Unknown” (*1/2 out of four) was a lifeless drama that deserves to be left in the unknown about a determined astronaut (Mark Strong) on a mission to Mars that goes awry and leaves him stranded in space and forced to improvise to try and stay alive. Virtually identical to last year’s “The Martian” with Matt Damon but has no energy, pacing, or original storytelling. Strong is a solid character actor but he’s not charismatic or exciting to hold the screen for nearly two hours on his own. After this and “Interstellar”, maybe we can do without outer-space pictures for a while.
