Exactly, I always looked on the ending not as Sam never getting to come home, but that he got to keep on leaping.
I was too distracted by the episode’s what-the-fuck factor to form an emotional response.
“Oh, Boy!”
Having already leaped into the body of an ancestor, he leaped into the body of a descendant, the captain of the Enterprise NX-01.
Does that mean the shadowy temporal cold war guy we never got any answers about was an evil leaper?
Again, the bartender says
“I’m not God, Sam”
Bit of an odd thing for him to say if he was God, dontcha think?
All this talk about quantum leap, I noticed the dates and how it kept getting closer to…I felt like leaping back before 9/11/01 and…yea, Oh Boy! 
Do you really think casting Bill McGill in the very first episode and then the last episode as the bartender of pure coincidence?

No, not a coincidence at all since other actors from previous episodes also appeared in the finale as different characters.
I would have liked to have seen an additional season. The “harder leaps”, Al as a happily married man, perhaps Tina married to Gooshi.
