From the plot summary:
Detective Harry Hole investigates the disappearance of a woman whose pink scarf is found wrapped around an ominous-looking snowman.
It is so odd and ironic that in history where the fact are known
and written down, that Hollywood can never get it right. They have
to change and mess with every small thing in order to make their
movie versions of "true stories" as they call them.
But, when there is a book and something doesn't make sense, they
go straight with it. Harry Hole is a stupid name that turns off
viewers ... it's like a permanent joke at the wrong time.
So, you are fine if someone thinks of a totally ridiculous name for the hero of some book or TV series ... they have a choice as to what to call their characters, and when they settle on something that is ridiculous, it ruins the reality of the book.
it's ridiculous for 5 minutes then you get over it, as it is in real life...
Early in my career we had to do some work for a major international client on a cross border deal, the CEO of their company was called Ashit... not joking, it's a real name, i had to google it... I think it's an Indian or Bengali name... Believe me, people took him seriously and it didn't matter if they were a partner at an top American law firm or European public officials. It didn't matter what the initial reaction was... The guy was a charismatic and powerful business person...
Why should movies be less powerful or interesting than real life?
A lot of people pay a lot of money to consulting firms to invent the right name for their companies. Like the Ashit example, a lot of words have some connotations you don't think about when you name them. Like the Chevy Nova ... "no va" means "it doesn't go" in Spanish. On some level you lose business when something tweaks your unconscious mind so.
... OK, another example, a restaurant in our town was named "Bird Dog", for some reason I forget now, it make sense to the owner. It did not last the year, and it was a nice looking place, even had good food they said. Who wants to think about dog when you are dining out?
