On Criticality

So, I do this reactor thing, and it turns up a good number of instances of Did Not Do The Research (WARNING: TVTROPES) in movies/fiction. For the most part, I ignore them and watch the thingy. Sometimes, they make it 'better' (OH GOD ATOMIC RAY GUN WHY). However, there's one that bugs me enough that I want to post about it: the word 'critical' does not mean what some scifi authors think it means.
( Cut for Reactor ramblings )

And that's my ramblings for the day. All comments and criticism welcome, particularly if I messed something up in the writeup.
