SPOILERS***Didn't ANYone else find the ending...
...more than just a tad hokey? I mean...Claire orbiting the earth in a Greenpeace satellite? And no friendship at all between Sam and Claire, but a birthday greeting from 3 relative strangers in her life? (Eugene excepted). Sorry...it just didn't ring true to me.
