Someone on Metafilter recently linked to a Twitter account called Hard Sci-Fi Movies. SF movie plots + slightly harder science – huge coincidences and plot conveniences = hilarity.
The Metafilter thread is just as much fun, if I do say so myself. Lots of great skewering of famous plot holes there, and mundanifying of outlandish SF. And probably a few good ideas for scenarios in there somewhere.
All of which is to say, I may not have time to write more for quite a few days. Hopefully I’ll be back at it early next week.
