There's plenty of the usual Hallmark checklist items in the movie, but a few new twists raise it above many (for example the last two scenes as well as the 'best friend' being a new acquaintance). The plot and characters could easily be built on so they should do a sequel. The young married couple could also have a movie of their own, maybe a prequel. Either way, there's a lot of cross-generational fun to be had.
