three nit-picking things-spoilers
1. I was irked that the parents told the daughter about their separation plans when they did and potentially spoiled the wedding. The daughter came upon her parents when they were having a very minor disagreement, barely noticeable to others, and they could have easily brushed that off. However, for purposes of the plot, the writers made it into a big deal. There should have been some major catalyst, like a big argument to make it more believable.
2. The swinging bridge wasn't THAT high.
3. The other parents were sickeningly sweet and lovey-dovey.
