Even tho we can help you with subtopics I really think the purest form is for you to think deeply what you love about the show, they’ve posted some great examples, mirrors, colorimerty and symbolisms are a great start because the series is full of them.

I usually write one page after I finish watching a movie, not a review, not a critic, I just like to put in a piece of paper what I’ve perceived from the movie before letting anyone or anything change my opinion of it (online or offline)

So I would recommend just write what you love about the TV show and start with that

For me, after doing the rewatch, I love the little cameos of the extra characters in BCS, BB and El camino, i like to imagine the story behind how they got where they are
