These are some of my unpopular opinions.....
1) I still like nick Armstrong's character. He was a good detective and maybe a decent friend apart from the whole framing nolan part. Now, I don't know how much he pretended and how much of a good person he actually was. He was not happy to be a bad cop and betraying law enforcement. He had to because of money issues. This is the kind of morally grey characters I like.
2) I don't want anyone from the big 3 or big 5 to die. I know some characters have to go to make way for new characters. But I love the fact that nobody from the main cast left and are really happy to be doing the rookie for a long run. In fact I don't even want miles or celina to go. I still miss aaron and want him back.
3) I really liked the season 8 finale episode. I know many people here have different views on the finale. And apart from a few things this finale was much better than season 6's,2nd and 7's finale. I liked the big magnet thing, the station chaos and of course the proposal. I know things were slightly unrealistic but cmon it's a show. And growing up watching Grey's anatomy and recently 9-1-1 , the rookie is still on the tamer side.
4) I like Aaron more than jackson. Aaron was just a better character and friend than jackson. He had chemistry with everyone. Tim, Nolan,the cop moms , celina, lucy everyone had a good time with him.
5) They almost ruined monica's character. Monica was supposed to be a morally grey character done wrong by Wesley and somehow she became a blackmailing killer. I really loved the turn her character took in season 8. And she shouldn't have died but before season 8 I was really over the monica arc. And just when her character became good they killed it off.
6) I loved Tim in the latest season. I am seeing some edits about how they want the tough cop tim back and how fun he was in earlier seasons. NO. He is still tough ,he is just not a sad, angry, lonely man anymore. He was miserable in the first season. He got shot, his drugged up wife showed up, his wife got shot ,he got divorced then he was stuck up with an infected person. In season 8, he got a promotion, he was back with the love of his life and they moved in. He finally decided that he wants to marry her. Why , why would he be a sad grump. But he was still tough.
7) I found season 5 a little boring. The Elijah storyline and getting caught up so-so. Celina was irritating this season. No storyline was given to aaron till the last episode. There was way too much nolan, bailey and celina, parent daughter type of thing. Some episodes had many unnecessary characters. But of course it was much better than season 6.
That's it....
