This is an episode with everything we like about the Chuck series with that special mix of action, fun and romance. We were waiting for this for a long time!
Now, the big and difficult question: should this episode be considered as the perfect happy ending for the series?
It has all the arcs ended: bad guy arrested, Mom freed, baby delivered, Chuck and Sarah engaged, Morgan in love, Casey fine, BuyMore geeks ousted.
I suggest the show to be stopped now in order to avoid any later disappointment.
Please, don't over-react and avoid rating this review negatively! IMHO, this is a real question worth considering. Other series were stopped after some seasons. I rather prefer a short and good show than a lengthy and average show. What do you think?
