I learned that you sometimes think "Hey, wouldn't it be nice if movies didn't just feature Hollywood prettypeople but instead normal, average-looking humans?", and that that thought is wrong.
I learned that
something that has
some kind power apparently does evil for...
some reason. Seriously, I don't need a complex backstory, but more than "just because" would be nice. "The Dark Power" had more lore than this!
I learned that, for the nth time, a movie does not know
how a garbage disposal works. They do not have whirring blades inside! They do not chop of fingers or arms! Stop that stupid, stupid trope!
I learned that you can allot around 90% of your movie's budget to - admittedly pretty decent - special effects, but then have nothing left over for the writing.
