Sci-fi Movies - Age and Expectation

Warning: Long post ahead, not to bash prometheus but to set expectation for sci-fi. If allergic to big posts, Run jonsey Run. I am observing some of the people posting their reviews and the expectations they had from the sci-fi movies these days based on their experience over the last two decades. Here is something I have observed. I am born in 1984 and I have enjoyed all the old sci-fi movies pre 90's which people even miss today. But there is one thing i have noticed among people who born before me and those who born after 1990's. People who are born after 1990's have very less expectations towards the plot, characters and dialogues. Give them anything that explodes and eye candy stuff and they'll enjoy it. *cough* micheal bay *** In case of 90's people, all they need is eye candy and quick fun. You can't keep them on cinema seat for 3 hours even if it is masterpiece. Some will moan about film being in depth and if the movie is finished in 1 and half hour, people will moan about less in-depth charcaters. There are some movies like prometheus where focus is on the extra terrestrials and less human characters will be entertained other than heroes. In case of 80's and pre 80's folks, or shall I say, retro folks are the ones which have a lot of expectations. They don't stand much of eye candy stuff and they need characters, plot and progressively developed sci-fi. This is the reason I think Alien may not scare these people but 3D in prometheus entertains for sure. The reason movies like hunger games, transformers and battleship are going to make more money than Alien, space odessy is because these are more of eye candy and pop corn movies. People don't have much time for speculation and hype these days like back in the days. Don't expect master piece sci-fi in the eye candy CGI decade. Just enjoy the new ideas and keep the [i]expectations[/i] in check. This is 2012, we're going to get sequels and prequels just to waste money over eye-candy and sensationalism.
