Near perfect

I was on the edge of my seat and clenching my thumbs at the end of this movie. However I wish there could have been a little more editing to make it perfect. Cast - There performances where fantastic without questions, well done. The character's though... Shaw and David - Great characters and well done. Shaw's single minded need to know why the engineers changed their mind related to her father dieting when she was young was a simplistic, under developed, or should have been dropped, abandonment syndrome. Vickers - Who doesn't want that life boat. When she reveals she is Weylands daughter it's just to direct and forced. There could have been some more foreshadowing there, maybe a e-photo on one of those fancy pocket tablets, nothing so direct Weyland - Not much to be said, he wanted to meet his maker and live forever, isn't that worth a trillion dollars and the destruction of everyone else? Perfect character. Holloway - This was by far the worst developed character and why I am posting at all really. How could a scientist character that has devoted his whole life to finding alien life, going to an alien planet, finding aliens civilization and then..... he becomes a drunk for 10 minutes, then becomes a raving lunatic for 10 minutes, then becomes macho man and has that love making scene with Shaw. Really bad. And that whole sex scene should have been re-done, we don't need to see kissing and a 60 second love story in the middle of this epic adventure. They could have just implied that they got together and then we could have seen the morning after. Janek - He was a good character though a little too quirky. He dark and devoted side was great, they could have just done away with the cute remarks, again this guy is ready to kill himself if necessary to protect the ship, give him a little more credit, and depth. Fifield - This character could have been toned down just a little bit but a someone had to be stupid and be killed first. Too much like the crazy marine turned scaredy cat in Aliens "No way man, I'm out of here man" remember him? Love Sean Harris in the Borgias. Concepts The shard storm was amazing. Well done. When David is standing in the control room gazing at the galactic projection is he going to really be able to reach up and have the earth land in his hand, then have it move with him like a 10 year old boy looking up at the night sky? Really. That was so cheesy. Holo projections flashing up everywhere? Why would this happened, why would the engineers/aliens have the recording system and why would it randomly play back scenes from 2000 years ago. It seems pretty evident that these where pretty adversarial folks and would not want their secrets played back to any random aliens (human) that happened upon their complex. OR where their two factions of engineers, one fighting the other and this was a way to seed the story for the humans (and the movie audience). This should have been better explained or not had it at all. It's similar to the dialog track of the original and editors cut of Blade Runner... do we need Harrison Ford tell us what is happening or can we just try and figure it out. Of course figuring out why any of this has happened is the big question and that is where I feel lost. Hopefully these questions will be answered.
