First of all, did anyone actually see this movie? (it's from 2000, according to IMDB) Well, I rented it recently, and...
I'll just get into the most striking questions here, as I certainly don't want to see this movie a second time to examine it any deeper. [img]/phpBB/images/smiles/icon_wink.gif[/img]
1) The protagonist's spaceship is hit by what seems to be debris off a comet's tail. While I won't question now a)why they were travelling at such a low speed so close to a solar system at that time and b)why the hull plating, though it could seemingly survive a re-entry at some wierd angle, did not stop them (yes, i know even grains of dust can leave huge craters at those velocities), the protagonists call it a "stray meteor" later. I spare you the meteor bit, but "stray"?
2)The ship is crashing on a conveniently near planet (why it is crashing in the first place is not questioned here, though it is a major plothole). Although it has about the same aerodynamics as a brick, they eventually manage to slow it down by jettisoning half of their ship and using airbrakes. Hmm. Anybody else got a problem with this? (I still don't know how they even managed through the atmosphere with holes in their hull and at what looked like almost a right angle...)
3)They discover they are on a planet which is apparently in a trinary solar system, with two reddish twin suns orbiting a bright blue sun (or the like). They claim that because of this, it's never night on the planet (You see this all very graphically on a toy planetarium in an abandoned mining colony, so I'm not assuming anything here). Actually, that would mean the planet is not orbiting any of these suns at all, but would have to stay in between the suns at all times. Hmm.
4)While we could still assume this as true, there is the matter of another planet - a Saturn-like ringed giant, which is so close to the other planet that you could assume the smaller to be a moon of the bigger one. This planet is the reason that every 22 years, when the blue sun has set, the two reddish suns go into eclipse behind it. And, as the two planets are "moving as one", this eclipse is said to last quite long.
Now, we see the red suns setting and the blue sun coming up before, so the day cycle can't really be so long that one spot on the planet can be in shade for that long (or I'm just too lazy to think up other scenarios where this is possible). Also, for such a wierd system, 22 years seem quite long a time for this to happen...
But let's stop this. Only one more point that I really found ugly:
5)When the red suns go into eclipse, you see the big planet rise on the horizon. Not only it looks huge, it's also darker than the rest of the sky, and the rings are clearly visible as the suns are shaded by them.
Hm... I never saw a dark moon rising in the sky... and though I have seen a total eclipse, I never saw the whole disk of the moon unless it was completely in front of the sun. I could assume you can see the planet as it is being lit by the other sun, but it is clearly much darker than the rest of the sky, and this is just Bad.
I guess I should stop this now... if anybody has anything to add, I left quite a bit of other questions that popped up during the movie. Those were just the ones that hurt the most.
