It does take a while for the characters to settle in, but once they do omg. Seasons 2 and 3 I was all over. Season 1, there is a good arc starting with The Man on Death Row (ep 7). The Christmas episode (The Man in the Fallout Shelter, 9) is so much fun and we get to see characters' families and stuff :D the first few eps are okay but I was reading the list of the rest and I remember really enjoying them. Then again, I watched them all marathon-style, so I was pretty focused on characters more than plot. Season 2 just has some awesome, awesome things going on - the best ever is 2.09, Two Aliens in a Spaceship. BEST EVER. ever.
so yeah, it's a light show, that is sometimes really exciting I think, and other times just like, Oh, okay, another mystery to solve for the team.
Bones' anthropology-fail is what bugs me the most. When she's like, I think this because I'm rational! WRONG, that is not rational right there! Or when she so obviously values and understands other cultures' practices and values more than contemporary Western and American.
