It started bad with Tennessee's joke about boobs, yes boobs...In an Alien movie. *Sigh* Then we had the back burster scene, which was good and gross as **** when the dudes spine came out and I was glad to see the parasite was quite small, believably small like the original baby Alien. Something which really annoyed me in the very end sequence of Prometheus when the alien - Deacon - burst out the engineer after being impregnated by the giant squid. That thing was huge, like how could that actually fit inside the engineer, it was ridiculous.
The bit I did not like though was when the parasite attacked Karine who was armed with a knife, she even booted the thing against the wall yet it still manages to kill her whilst its the size of a jack russell. Okay it was vicious but come on, you'd just grab it and stab it to death. Bit daft that bit I thought.
Although I did like the gun going off when she slipped on the blood, that was quite good. It was done just about right but only just so it didnt cross the line into tongue in cheek comedy.
The second death with the neck burster was pretty boring I thought, not enough suspense, shock and disgust. It just burst out and ran away. Yawn, come on Ridley, try harder. I want you to shock the **** out of me, like what it must have been like to see the Alien chest burster scene for the first time back in 1979, dont cheap out.
