Is IU having a hard time with movies?

First of all, it doesn't seem like she accepts every drama offer she receives,
but I suspect she's likely only reviewing lead roles.
Perhaps because of her music career,
it feels like she's intentionally not doing dramas very often.
Considering her recognition and popularity,
she must have received movie offers,
but I wonder if she's turning them down because they aren't lead roles,
or if the scripts just don't appeal to her.
