Well we got a pretty shocking ending to the season to say the least. The Big Bang Theory has clearly gone downhill but this was a quite satisfying finale. I really did not expect Raj & Penny to hook up. That is something I really never thought would happen.
Now I'm looking forward too the future dynamics that arise because of this. Woo-hoo for Priya moving back to India! I'm sure everyone enjoyed that. Also the Bernadette & Howard relationship is in trouble; I personally am not a fan of this pairing, so I honestly hope they break up and Bernadette fades out like Leslie did.
I felt like we could have used more Amy in the episode, but I'm sure a lot of people will disagree with me on that one. The closeout scene was perfect, really got me pumped for the fifth season. Hopefully the show proves to be better next season. Good finale.
