Watched it twice, cried both times. Probably could have had a few minutes cut while still tight if you care about that kind of thing, recommend watching in IMAX since it's a space movie. One notable annoying science inaccuracy that felt particularly blatent was jurer gur pragevshtr jnf haonynaprq sbe ab ernfba but that's forgivable.

Just came back from the show. Loved it. Might go back for an IMAX viewing. I liked the book as well, and thought it was a good adaptation.

Cried a lot.

Yes. I really enjoyed it. Visually spectacular, pretty faithful to the book (as far as I remember the book) and Ryan Gosling was very good in it. They were even fairly faithful to the laws of physics (relative to other Hollywood movies, anyway).

Yeah, my wife and I saw it earlier this week. I thought it was an excellent adaptation of a very good book. My wife, who hasn’t read the book, didn’t like it and took a nap. (I think that’s a pretty minority position for most people who have seen the movie without reading the book.)

The book is very good and the movie is pretty faithful to the book. They did an amazingly good job of making Rocky into a real character.

Exactly. An no tiring unrealistic villain arc.

I hadn't read the book nor watched any trailers (I hate trailers with a passion), so tonally it was a fair bit lighter than anticipated. However both me and my unsuspecting victim of a movie partner (she isn't typically into scifi) really enjoyed it, and I had a similar sentiment afterwards.

Saw it on IMAX, and did not regret that choice one bit.

I read the book on release and loved it. The main themes and plot points are present in the movie, though it's overall a bit less nerdy and a bit more comical than the book. I think it is easily one of the best, most enjoyable sci-fi movies released this decade.

It’s a movie, not a book. The audio book is 16 hours runtime. The movie is 2 hours. Some things were always going to be left out. The details of the science stuff was one of them. It works better in a book narrative where the process is told than a movie where it’s visual and you have to show.

The Martian book has more of the science process than PHM book does to begin with.

The movie hit all of the primary points but never got into the details. If you read the book you can fill in the details. I imagine that a lot of people watching the movie didn’t know why some things were happening. Maybe some will be interested enough to read the book or the audiobook. If not, they had a good experience in the movie anyway.

It’s still a really good movie.
