Eh, they should stop making these. They'll never recapture the magic of the first 4. Michael Fassbender and Danny McBride were the only good actors in this film... Danny McBride, let that sink in. He actually did a surprisingly good job of being something other than an arrogant buffoon he's type casted himself as.
They basically threw out the whole lore of Xenomorphs and did whatever the hell they wanted to in this film. Now you can get chest busters, back bursters, and mouth bursters in several different ways. They come out as mini Xenomorphs now, instead of the traditional chest burster... even if someone gets facehugged the old fashion way... nope. Mini-Xeno! and then they become giant within seconds? I mean, I know they grow pretty fast... but hey lets make it even faster. And then lets take one, stand in a circle around it a shoot 1000 rounds into it, and magically no one gets shot or bathed in acid blood.. just one person dies because of possibly a tail swipe, but you don't know really until you get it on DVD and do it in slow mo.
The mystery of the Xenomorph's origin is ruined by some lame explanation.
Most the characters are idiots like MyK said... and the ungodly inconsistency in one of Fassbenders characters was so forced to try to make suspense, it didn't work because it was obvious what had happened. The end was shit. I probably shouldn't even use a spoiler tag to save you the money, but I'll do it.
This film is pretty much a direct sequel to Prometheus.
