Title drops in movies

Intentionality matters. "It" should not count as a title drop. Nor Barbie (or any movie where the title is the characters name). But I understand it would be way more difficult to run the numbers with such a constraint. But this is a case where, to me, the results are very much tainted and thus I had to stop reading. To me this is like when developers run into a hard issue and somehow play a game of semantics with the wording of a ticket to avoid putting together something useful for the user

While it is somewhat arbitrary, I am sure that "Barbie" is intentional, the somewhat obnoxious repetition of the word "Barbie" fits the theme. Also, maybe you stopped reading a little too early as the case where the title is a character name is specially addressed.

"It" may be the the special case here, as it is a very common word by itself but that a movie is named like this is notable enough for it to be included.
