Great movie. Great concept. Good casting. Great writing.

Rating: 9/10 (29 July 2018)

Although there is room for improvement, this movie hits well on all cylinders. People need to accept their will never be a perfect movie, which is why I gave this one such high marks. Two movies I consider a 10 are Titanic and Avatar. There are more but these are two examples of my version of a 10,
The Martian provides an excellent blend of drama, sci-fi, and comedic moments that are not over the top. The casting was great with the exception of a few roles. There were a few space scenes that are a total farce, but overall they did capture the essence of what it will take to go to Mars.
My rating is actually a toss up between 8 and 9 stars.
