You just paid $15 to go see a shitty mockumentary scary movie..and it ends rather abruptly with something along the lines of "Go to our website to see more" ROFL

1. They explode (cos their bodies can't convert to vitamin D when exposed in sunlight),
2. Oftentimes, they turn to stone when they're older and their bones expand inside their bodies that their veins become to narrow.
3. They EAT people who have Christian blood... Ha, Anti-Christian Trolls eh?
4. Some can grow 2 more heads like the type in Greek myths of Hydra and Cerberus.
5. Any weapons like HUUUUGE spotlights and bazookas can easily kill them.

a ghostly return warning to the other astronaut not to land in Europa. And his transformation from young to old to the space fetus with his faded static alien voice just made me shit bricks badly. There's even one scene that reminded me of Poltergiest when Dave talked to his wife in a TV set in a very creepy static voice..

they're like the ultimate stargates that when they multiply in Jupiter's atmosphere, they turn into one big scary ass BLACK HOLE that really suck the giant planet and BOOOOM A STAR IS BORN.. Literally. And of course, when the Russian astronaut decided to dock himself near the monolith, the guy just sucked in much like a black hole and WWOOOOSH it warped into another universe. Much like the time warp stargate sequence in the 1st when Dave first experienced it.

HAL 9000 is back in this one and the explanation of what he did in the 1st one was obviously the faulty stupid government orders of keeping secrets and killing of astronauts. also, the spaceship Discovery behaved like ghostship similar to the later ones like in that movie, Event Horizon.

It almost went the same route like the 1st where the apes in the prehistoric earth first discovered the monolith except this one is in one of Jupiter's moon Europa in a swamp with no signs of life yet.. Although Jupiter is now officially a giant bright 2nd sun star. The 2001 theme music really suited its background epicness.
