I was watching waterworld ('bought' 340 movies in the last couple of months thanks to my speedy internet upgrade)
and I found an error in the movie. I don't even fucking remember what it was
but I went online to see if anyone else caught it, and I ended up going on an adventure
I found myself at a page where nerds write in all the technical and story issues they have with a movie, and a kindly adult dismisses them handily, but politely
it is just delightful:
