I thought the ending was very uneven. There were elements I liked and others I didn't. I still cried.
I always thought Penny's "I don't want kids" never rang true, so I was really happy she was pregnant at the end. And in any event, the pregnancy was unplanned.
I hated Stuart's incompetence taking care of the Wolowitzes' kids. He took care of Debbie, and he'd been their nanny for a long time, so he should have been fine.
I disliked the ladies talking quite loudly on the night flight about Penny's pregnancy. How rude to the other passengers.
I liked Amy telling Sheldon off, and both their speeches at the ceremony.
What was the point of Anu? For that matter, what's the point of an arranged marriage if you don't actually, you know, get married?
I would have been happy if Raj was happily single, but he still wanted the unrealistic movie version of love and marriage.
Someone mentioned above that we were cheated of a Raj/Amy shopping montage; I agree. That would have been cool. And to the tune of "Pretty Woman."
You don't believe people remain friends for decades? They work together and they see each other daily; they're in each other's lives constantly. Friendships can and do endure.
