I don't hate all of it, of course. You get some good movies every once in a while. This isn't going to be about bland, generic action flicks, cookie-cutter CGI cartoons, craptacular remakes of classics, or any of that in this post. This is about the sorts of ridiculous things people end up believing because they saw it in a movie.
Nothing terribly new in this rant. Fair warning: Lot of TV Tropes links below the fold.
First up: Hollywood Evolution. I even complained about this when it showed up in Star Trek series I watched and enjoyed as a kid. I know there's no such thing as 'evolutionary levels' or any particular direction evolution should go. I wouldn't be surprised if Hollywood is feeding into a lot of Creationists out there who think there are platonic eidolons of 'smart humanoids' that everything's 'supposed' to evolve to. Sooooo...
EVOLUTION DOES NOT WORK THAT WAY!
Thank you, Morbo.
Next: Space. This is a collection of relatively minor complaints, since it's not quite relevant to our everyday lives, yet. The cumulative ignorance annoys me, though. Space is silent. Space flight is not like aerial flight. Firefly got big bonus points with me for depicting space silently. Of course, you end up with a lot of this sort of stuff afflicting Moon Hoaxers. If you haven't read classic Bad Astronomy, I highly recommend it. He's gone over plenty of other stuff that miffed me.
Elements & General Chemistry: 1. We've got a lot of elements on the periodic chart. You've going to have to get creative if you're going to add another. 2. I don't know any green acids. The big ones, hydrochloric and sulfuric are clear. They look just like straight water. Of course, they have to be mixed in water to be acidic.
Nuclear Physics: Blowing up this sort of stuff takes effort.
Sci-Fi Writers Have No Sense of Scale: Energy subcategory. I think this is one contributor to all the doomsayers about the LHC. The collisions there involve very little energy or mass. Of course, Hollywood loves to have MacGuffins and such that could blow up planets despite being suitcase-sized, or phlebotinum that can readily defy thermodynamics.
I'm sure you've got more complaints.
