Nothing wrong with a good quality ND filter.
By removing two stops of film speed flexibility and creativity is

Well, apparently a lot of people believe that faster is better - all other things being equal - because so few of them bought ISO 25 film that it wasn't worth it for the manufacturers to continue it.
