"The Newsroom" and "Prometheus"

My friend loves the Alien movies and I love going to the movies, so tonight we went to see Prometheus. I've got a lot of problems with this movie. The main thing is- it doesn't make a lot of sense. No, it's main problem is that it's slow and almost unwatchable. Halfway through, and then especially towards the end, I just wanted it to be over so I could go out and have a cigarette. Prometheus is really two movies: it's a movie that asks questions about where humans came from, and it's also a horror movie about Alien-type creatures attacking people. Here's something that bothered me: during the opening credits I saw "Guy Pearce". I was pretty excited; I like him and haven't seen him since The Rules of Engagement in 2000. He was so good in that. So I watched the movie and forgot all about him. Then during the closing credits I saw his name again. Oh, right- I forgot about Guy. So, who did he play? Then I realized that he was the actor under all the old person make-up. The movies are not good at aging people. I'm thinking about The Godfather Part III and A League of Their Own. The only example of good old-person make-up is Father Merrin in The Exorcist. The funny thing is, now that he really is old, he looks just like Dick Smith made him look in that movie. By the way, this past weekend I saw both the first episode of The Newsroom and Aaron Sorkin on Piers Morgan talking about The Newsroom. The show was exactly the way I expected it to be but I'm not complaining. I don't know if I'm gonna like it as much as The West Wing but I think it will be good. Anyway, Morgan asked Sorkin about acting and good actors and Sorkin said that one thing that actors can't fake is being smart. I agree and there's a good example in Prometheus. I'm not saying that Logan Marshall-Green, the guy who plays Charlie Holloway, is dumb or stupid. He's probably pretty bright. But in this movie he was playing an archaeologist and I didn't believe it for a second. You watch him and you know that he hasn't read a book since he was a senior in high school. It isn't Green's fault; he's just mis-cast. By the way, through the whole movie I was trying to remember where I'd seen Green before. It wouldn't come to me so I looked him up when I got home and then I found it: he played the guy who made it to the end in Devil. Before i started writing this I looked up Prometheus on Wiki cause I was confused about the story. I still don't understand why people (and robots) did the things they did, and I'd like to find out, but I'd like to find out in any way that doesn't involve watching the movie ever again.
