I love this show because it's so different to the original as in my opinion it is too procedural and I just never got that invested in the characters.
Whereas NCIS LA is totally different. This show has a 24/Scorpion feel to it. It doesn't just deal with homicides but drug cartels, terrorists, kidnapping etc. They often have cases that take them overseas, threaten their lives or nation security and are always going undercover as they are a covert branch of NCIS.
The characters have interesting back stories, especially Callen and Hetty. The introduction of Marty Deeks at the end of season 1 was genius and created a comedic element as well. Kensi is a great character as well and I like the nerds, Eric and Nell.
So in my opinion this show has everything. Yes it's procedural in nature but has lots of back stories and arcs each season. You really become invested in the characters which I think is important in a tv show as you care about them and want to watch them develop.
The only reason I haven't given it 10 stars is because season 1 isn't as good as the rest and then most of season 9 is subpar but gets better towards the end of the season and then season 10 has been good. I'm excited for season 11.
