I thought Red Planet was kinda meh. I didn't regret seeing it, but it was totally forgettable popcorn entertainment. Sunshine was surprisingly good, until the ending, which sucked balls.
I can't fathom how any human being on Earth could like the movie THX 1138. It was just unspeakably boring and mind-numbing. It also never ends. The movie will go on and on forever until you either turn it off or fall asleep watching it. Maybe I should give it another chance, because it did have some good moments. But mostly it was just .... stuff happening, stuff you had no inclination to care about nor any desire to see what would happen next.
But really now. I can't stress how good this movie is:

Get it now. It will change your life and the way you look at movies. It is absolutely the most underrated movie on IMDB, ever. It should be in the top #5.
