I'm very new to NCIS, both the show and fandom. A few days ago I finally finished a (very long) marathon of all 4 seasons and I posted some thoughts on each season as well as my favorite episodes and scenes on my journal. I would love to know everyone else's thoughts on the four seasons, like favorite characters and pairings, or favorite episodes and scenes, anything really.
Be aware that there are spoilers for all four seasons, although each season is separated and labeled. There are some season 2 spoilers in the season 1 discussion, as well.
