lmfaoooo, yeah it's not a popcorn movie. If you approach the movie wanting to contemplate existence and what the future holds for humankind, you might appreciate it. (Dropping some acid during the flight to Jupiter scenes also seems to help some
) If you are looking for some solid entertainment that doesn't get too bogged down in metaphysics, then you'll most likely hate it.
I've urged a friend to watch it and he says he has tried on multiple occasions but keeps falling asleep.
Others I know love it, others hate it.
As far as a film goes, its definitely not my favourite, but it's a movie that was way ahead of its time and contemplates some issues which are still relevant to this day, especially for those who still believe in progress, evolution, artificial intelligence and the hope in space exploration and discovery.
