It was great to see all these actors again, and with a happy ending. It certainly isn't Shakespeare, but there is a cute story with all three couples. Just don't get hung up on the fact these actors were in previous series together, there is nothing in common with those other characters. There really aren't any loose ends or major holes in the plot, which is nice for a change.

Simply take this as a new short movie, and it will be a fun distraction from the real world for a couple hours.
