NCIS series Premiere, did anyone else watch this?

It seems to me That Ziva was a little unhinged, she accused Gibbs of abandoning her, but she is the one who left the team and then was pronounced dead when her house was bombed and went into hiding. She hid everything and did not reach out to him until she needed help killing this person, who she claims was trying to kill her. At the very beginning there was a shootout at Gibbs' house and then after that any violence was started by her. She just did not seem the way she was when she was on his team. Anyone else feel that way??
