Please do yourself a favor and avoid the last season.
The show is genuinely nice, clean, with a strong message. You really want to live in Middleton, have around people like Cassie strong, independent, caring. But suddenly she got married again and Grace goes to college, and she becomes a sad lady, whining and suffering all the time, forgetting about the people around her, the last season doesn't have a good fit. All these leave a bad message about marriage is, like is she was better as a widow before. Marriage is not the solution but never the cause! Sadly, Hallmark seems to be rushed to finish the series
