In my opinion, I don't think that they should've killed Michael off. What him and Jane had was so special and romantic. Although, she did leave him and got with Rafael, he still cared about her and was always doing things to help her. I haven't seen season 4 yet, but if she doesn't data the guy that appeared at the end of the last episode of season 3, then she'll probably get back together with Rafael, and they are cute together (don't get me wrong), he also has children with Petra and that will cause tension once again, because when she first had the kids, Jane thought her and Mateo would be...
I really like this show. If were to finish a season I would watch it all over again. I don't know how to explain how much I Amore this show. If te haven't finished season 3 then i wouldn't keep on reading. That part where Michael had the stroke and died got me really good and also how desperate Jane she first found out that Michael died. I just loved the way Rafael was just entering and how he hugged her. 3 years later was the best Mateo got so big but Jane doesn't disaplend him which kind got me frustrated.
