NCIS
Definitely my all-time favorite series. And it was for many years but not anymore.
I'm currently re-watching it from the beginning due to having the first 13 seasons on DVD. I'm amazed how incredible good the firts seasons were. The dialogue was sharp and the episodes very exciting. It lost some of that later on but was still great untin the disastrous season 18 when everything started to go wrong. I must also admit that I miss Kate even if I like Ziva too.
The series took a heavy blow when first Ziva, then Tony and then Abby left. But successors like Ellie and Torres were actually very good. But it all ended when first Jack, then Ellie and Gibbs left and were replaced with .....not so good characters. I don't watch it anymore.
Which is sad due to how long I liked it and that I don't follow any series anymore. They are all so bad now.
However, I do have seasons 1-13 on DVD and will buy seasons 14-17 too. In this way I can still watch this fantastic series when it was brilliant.
Yeah, I'm a huge fan of the show too, but I do disagree with you on a few points. I love the current characters we have just as much as the characters from the earlier seasons. I honestly never really liked Kate, to the point that when USA or one of the other channels is reshowing episodes with I won't watch them.
I'm enjoying it now just as much as I do years ago.
NCIS Red
I never saw anything of it.
I thought the backdoor pilot had a lot of potential, and I'm a little disappointed it didn't go to series.
NCIS Los Angeles
I watched it from the start. Good series with good characters but not as good as "original" NCIS.
However, the series took a turn to the worst when hetty left and was replaced by the horrible Mosley. I hate those "new boss coming in and starts screwing up for the team" scenarios.
When Nell and Eric left and was replaced by bad characters it was over for me. There are at least one of the nwe characters I simply can't stand.
My absolute favorite of the franchise, love all of the characters and cast.
I thought Mosely was OK, but I was glad when Hetty came back. I don't mind her being gone as much now that we have Killbride on full time as her replace. Gerald McRaney is just perfect in the role, and he has quickly become one of my favorite characters. While I do miss Eric and Nell, I really like Roundtree and Fatima a lot.
NCIS New Orleans
I liked it from the beginning. First of all because it was set in another town than New York or Los Angeles and also because of the interactoion between Pride, LaSalle and Brody. I liked Loretta and Sebastian too.
But I started to lose interest when Brody was dumped because of a stupid decision from a stupid boss and was replaced by a character I didn't like. later, when everything started to be about Prides brain ghosts and LaSalle left and was replaced by a weak character, then it was over for me.
NoLa has always been my least favorite of the series, I just never found the characters or the stories as good as any of the others.
NCIS Hawai'i
I watched six episodes of this series when I decided to quit.
The characters are so uninteresting. They are all the same and the series looks like a bad copy of Hawaii 5-0.
Really like Hawaii a lot so far, it's surpassed NoLa for me, and is at least equal with the original.
NCIS Sydney
I will check it out with some hope that it will be watchable.
But due to the low quality of all 2020's series, I have my doubts.
Really looking forward to checking this out when it starts.
