Overall I rather enjoyed it. I think the show can be broken up into two different shows, the one where Greene is on it, and the one where he is not.

While the later seasons were good, the show shines best in the first eight seasons. I really enjoyed season 15, I think it was Noah Wyle that I enjoyed more than anything else. The chemistry between the original cast was hard, and at times impossible, to replicate.

A lot of the characters grew on me.

Things I did not like:

Killing of Gallant

Getting rid of Ray

Killing of Romano

Every time a new boss shows up, the entire team hates them.

I'll probably watch it again, but maybe just the first eight seasons, Carter's time in Africa, and then season 15.
