hahaha....
to some people it's stupid...and to others it's brilliant...
just watch it today...
and i would say it's a good film...not great
maybe because there's already too much prequel film being make...
and as a "alien" fan myself...my expectation is quite high
but it does answer some question in about ridley alien film

p/s:
i like how ridley still maintain some originality between alien and promethues
for example..the costume still in some "grunge/rock" style or casual type of cloth
just like we can see in all film in 80's and early 90's...
and the interior design of the ship also is not much different between the original alien
unlike some other sciene fic movie...the original is not so high tech...
BUT when it come to the prequal...seems the tech become more advance

hahahaha...
relax guys...
any film/movie is just an EVENT TO MAKE BELIEVE
some will believe it some don't..
and clearly it's science FICTION

and after seing all the comment in this forum and all over the internet...
i think the movies really DID GOOD JOB
their marketing strategy is GOOD...it leaves more question than answer..
so "some" people will still looking foward for next sequal in the franchise
