So quick to judge. For all you know, I could have Ripley showing up in Part 2! (I don't.)
As far as Part 1, I didn't figure anyone would want to see a female chestburster scene after Prometheus, let alone a woman getting her skull melted off. But okay, whatever floats your boat...melted-face female security guard it is. (Sorry, Lieutenant Williams - I was quite enjoying your web series.)
Working on Part 2 now. If I don't have it in by tonight, I'll get it by tomorrow.
LOL! I could have stomached Prometheus if the characters hadn't been so astonishingly stupid on every level and the lead character hadn't been quite so acrobatic with massive surgical stitches in her.
Currently watching the Last Ship - that is doing a much more intelligent job on using sensible isolation protocols and very good use of female characters.
I confess, I was very tempted to do a Rand as Ripley scene but I didn't have sufficient screenshots to pull it off lol. Do you thnk pasting Rand's head on Sigourney's body would work? If you are going to do it, she has to be in her pants.
Your story is cool. You are ramping up the tension and raising the stakes nicely. If you want to ramp it up a bit more, you could try introducing a bit more personality into a couple of your redshirts so the audience starts to care if they live or die (and don't kill them straight away if at all) - making one an alien helps make them more interesting IMO. Also you can place one of your 'regular' cast in peril and have them function as eyes for the audience as to the horror of what is happening.
