no....but i've been reading about it for the last couple of months
and pretty much every review says basically that "although not a direct sequel the last 12 minutes will make fans of Alien jump for joy"
to be honest the preview makes me jump for joy.....i will be at the first showing on june 8th in sparks nv for anybody who ants to join me
i feel like it is going to explain why the craft was there.....but not why or where the "Aliens" came from (which could lead into a direct sequel....which Scott has been talking about for some time now

)
i've watched Alien twice in the last month to prepare myself for this
