I gave this movie a 9 and here is why--
Red Planet! What a movie. Yeah, some folks (if not the majority) simply do not like it.
But that is where I see gold between the lenses and cracks of the red rock. Red Planet is simply an entertaining movie that doesn't need to challenge the viewer as much as it drives them to a film that just wants to entertain you for two hours.
You could complain for the incompetent characters, the faulty science, or even just the pace that didn't deliver well on time. Whatever your ill-will is towards the film, is none of my concern.
Unlike's its twin sister -- Mission to Mars -- which is pretentious and overbearing upon the audience. Red Planet has a simple plot with interesting tech that gravitates a certain keen interest within me. When I watch this film, the philosophical view points, the scientific flaws, and the sometimes ridiculous action is all I want in a film that is not trying to pull a '2001' on me. It is, what it is.
Cheesy science fiction!
The actors do their best and often times succeed. The plot hangs in there without trying to be smart (which often can make it stupid). The music is fantastic! And most of all, it's a movie that you could if you're bored, waste time with and certainly not feel guilty about.
This is not a movie that will be an instant classic. This is not a movie that will be remembered forever in the annals of cinema history.
It is for all its worth, an enjoyable film.
