Ridley Scott's The Martian is a Too Much technical movie. Why people watch movie?? To enjoy it but this movie is like we learn some kind of NASA SPACE program.Too much technical story. That how to bring a Astronaut to the earth. Too much lengthy discussion. Ridley Scott not shown any challenge to the Matt Damon on the MARS just he grew some potatoes on MARS "This is what we gonna see in the Ridley Scott's movie" come on. He can show some alien stuff some kind of challenge. Now about the spl Effects the every big budget Hollywood flick is coming with good spl effects.The Sandara's Bullocks The Gravity movie is very good movie in every aspect. In Martian there is no Action there is not adventure just lame acting buy Vincent kappor and Jeff Daniels. i don't know why this movie getting 8.5 Rating on IMDb.Because its a Ridley's Scott movie. I gave only 3 stars out of Ten just because of spl effect. There is nothing to watch on theater you will waste your 2:21:00 Hrs. watch it on DVD
