Keeping this short....
I too, started off wondering were this episode was going. Yes, it is a filler. The usual back stories you get, regarding the lives of the key members of the team. Their past, what made them.
However, as the story unfolded, it became clear it was a remembrance of the horrific events of 9 / 11.
It was done well, it was done with care. It was done because of those life changing events the world has come to know, and remembering those who were taken.
Give it a chance, work with the story. It's better than most people think.
