it seems that most questions about the topic marker 은/는 relate to its distinction from subject markers.
I would like to ask if the following sentence attaching the topic marker to the object is correct (and natural):
기생충은 오늘 제가 봤어요
I realise that I could also have attached the topic markers to different words to obtain:
저는 오늘 기생충을 봤어요, or
오늘은 제가 기생충을 봤어요,
but since I want to steer the conversation towards the movie, I would argue it makes a lot of sense to attach the topic marker to 기생충. Then I might even follow up with 좋아요! (hopefully, I haven't watched the movie yet) and it would be obvious that the verb refers to the movie.
Is it possible to attach the topic marker to anything? Is it correct/natural when I place the topic first in the three sentences above? Are other word orders more natural?
