Good story and production but one major flaw

Rating: 6/10 (27 May 2017)

Whoever the genius was that cast Matthew McConaughey as a super- intelligent astronaut, completely funked up what otherwise would have been a highly rated sci-fi drama.
Sorry but brilliant scientific observations and explanations just don't sound credible coming from a typecast smooth talking lady's man sporting a redneck accent. It's awkward and I just couldn't get past it.
Russell Crowe, George Clooney... anyone but Matthew McConaughey and this might have risen to the level of "great."
