FWIW, I hated Red Mars as a novel. It had some interesting science in it but as a story it was way below par. The characters were not fleshed out well, the bad guys had no motivation, the chapters seemed strung together haphazardly with plot threads constantly left dangling. The "exciting finale" felt completely forced with a silly chase sequence that didn't seem to matter in the overal scheme of things.
Bad, bad book.
