Ridley Scott must have directed the entire movie drunk

Rating: 1/10 (24 June 2012)

I'm a huge sci-fi fan and also an admirer of Scott's work, but I'm probably not going to watch a movie solely because it was directed by him anymore. This was probably one of the worst movies I've seen in the past few years, including a few that were made for TV.
The screenplay seems to have been written by a 13 year old school kid. The plot has so many holes it's ridiculous, I was annoyed and deviated from the movie to the plot holes less than 10 minutes into the watching it, which is saying something. Here are some of the highlights that weren't mentioned in the reviews I've read:
1. It's a trillion dollar mission and basically no one in the crew knows what the hell they're doing there until after they reach their destination.
2. As soon as the crew gets out of their suspended animation chambers, one of the members starts showing an attitude towards mission command during their first briefing. Not in a million years would anyone with a dysfunctional personality be allowed in the most trivial space mission, let alone an important one.
3. It's important to decontaminate a specimens collected from the surface of the planet while in the lab, but the "scientists" don't wear their helmets while collecting it making the decontamination in the lab completely useless.
4. The reasons / motivations for basically anything in the movie are not plausible or believable leading to deep annoyance and boredom during the torture that is watching this movie.
5. The characters have either idiotic or psychotic personalities, some times both. Even in real life astronauts are usually extremely intelligent and able to cope with and keep their cool under stressful situations.
6. The plot development is painfully slow and a lot of the time doesn't make enough sense to be sufficiently believable that the spectator can get into it and forget about the plot holes.
My advice is, honestly, stay away from this movie at all cost. I know a lot of people won't be able to, and out of curiosity will watch this monstrosity anyway. But remember: you have been warned.
