^Maybe you're talking about a different article, then. The one I saw was very pro-Laurel.
Anyway, I have no dog in this fight. I wasn't crazy about Cassidy, but I have no interest in arguing about how the character was handled. I do think she was handled better this past season or so than in the past, although I won't particularly miss her and I didn't feel anything when she died (although that's partly because I expected it to be fake). But that's just me. Others are perfectly entitled to like the character and her handling.
It IS very pro-Laurel, but it's also from someone who is an unapologetic Olicity fan, and is a very objective analysis of the character's arc on the show.
