Even the most practiced writers make mistakes. Here’s one I found today, in Slashfilm’s piece “The 28 Best Movies of 2017 So Far“, in a section written by Ethan Anderton:
Romantic comedies are a dime a dozen, and most of them aren’t even worth that 10-cent piece when all is said and done.
Well, no, of course not. If they’re a dime a dozen, then one would be worth about eight tenths of a cent.
