Jake and Amy always felt forced to me, as if the writers needed a workplace romance drama and they were the best pairing they could come up with.
As for the episode itself, it was pretty standard-issue stuff:
primary couple finally has their wedding day arrive.
Last minute dilemma threatens the day.
One last adventure/solve to save the wedding day.
A last minute venue change to a simple location for the wedding.
All the cast-mates contribute to make the day special.
And finally....
Cue the sappy music as a contrived scenario takes place where everyone pretends that this subpar location is somehow magical.
And top it off with a shmaltzy diatribe meant to evoke emotions.
Now I'm sure this'll receive a large majority of thumbs down, but it remains true that this episode is just another standard sitcom formula played out with no real inspiration or heart.
