Despite some of the surprises we've liked and disliked at the end of season 3 and the beginning of season 4, it hasn't lost any of the attraction it first held for me.
The characters have only developed further, their relationships have grown stronger. They also depend on one another as well, then there are Hodgins and Angela. The two seem to be getting back to semi-normal.
Overall the tone of Bones has changed slightly, edging more towards drama than just crime, and yet it's still good. It gives us a sense of people and how they interact.
I love this show, and can't wait until the next episode in January, which looks hilarious. In fact, some parts of this show are absolutely hilarious and that's what makes it worth watching. (Especially Booth and Brennan arguing, and it only got better when they added Sweets.)
The only two actors I truly miss are Eric Milligan Jonathan Adams. I'm sad that they're no longer on the show. They really added something to it.
